Freedom Tenants
The Good (or at least the Alright)
Creative Expression (T1): A good foundational tenant for CV play, and solid culture provider. It does its job.
Economic Union (T1): Often best when combined with TR focused civs (Morocco, Portugal, Ottoman, etc), it can be a niche policy, but in that niche it does a solid job. TRs give all sorts of benefits, and if course if there are a lot of freedom civs in the game the gold bonus is icing on the cake.
Draft Registration (T1): Though it was severely weakened by losing the supply bonuses, the core bonus is still very useful, and frankly the only true military advantage that Freedom has.
Capitalism (T2): I don't always need more happiness when I'm going freedom, but this policy does manage it pretty darn well. What makes it good is it directly hits local happiness, which is often the biggest remaining happiness issue (especially for Tall play), and this directly addresses it. The +1 gold on specialists again is just icing.
Universal Healthcare (T1): Free is always good, and the free hospitals are nice for civs that are struggling on their infrastructure (which tall+artistry+rationalism often is, having all the techs in the world but not enough hammers to build the things tech gives you). And then the culture bonus continues your culture momentum.
Space Procurements (T3): For SV its a decent policy, as long as the rest of the tree gives you the science engine to get to the SV....the ability to buy parts can shave us a LOT of turns in the late game science race.
Treaty Organization (T3): Its a good DV tenant that does its job solidly.
Media Culture (T3): Its just alright, but if we plug some of the holes earlier in the tree it should still be good as is.
The Bad
Civil Society / Urbanization (T1): The issue is that both of these policies exist, and basically do the exact same thing. No one works food to really grow at this point in the game, its to run specialists. So instead of 1 good policy to do that, we get two watered down ones. We need to kill one of them and improve the other.
Avante Garde (T1): This is a policy that looks good until you compare it to its brothers in other trees. +33% to GP sounds really good, but honestly there are so many % bonuses at this that this bonus gets watered down.
Arsenal of Democracy (T2): Just to confirm I wasn't crazy, I did a quick check in my last game to see what arsenal would have netted me. So I can buy a diplomat for 520 g and get 110 influence, or gift a cheap zeppelin (510 g) for 51 influence. That's still a crazy bad deal, and of course there is the factor that diplomats at this point are super fast and can bypass borders, and can stack with other units so they don't get into traffic jams. This policy is not great for DV play, the +15% hammer isn't helping you out that much (you want to buy units not build them!)
New Deal (T2): Compared to per city bonuses in other trees, this one still struggles a bit.
Their Finest Hour (T2): Its alright but nothing sexy enough compared to other trees.
Transnationalism (T2): So this one falls in the middle between Order and Autocracy in terms of corp manipulation. Order gives you speed, the ability to have all of your franchises built instantly, ready to go, and the ability to ignore the franchise game entirely with sanctions and such. Autocracy gives power, you can in theory have more franchises than any other tree, and therefore the strongest corps, which is counterbalanced by a lot of work needed to get to those high numbers. Freedom provides quicker franchises through the 15% vs 5, which also bypasses the TR game....somewhat. So conceptually its fine but it doesn't hit either side enough, its not quick enough, or powerful enough, to compete. So some tweaks here can help.
Universal Suffrage (T2): I think the issue here is the bonus comes too late. Having a golden age when I'm just getting into ideologies can be useful, but by Tier 2 (especially on the specialist focused tree) I've got GAs coming out of my ears. I think if this one just came sooner it would have a niche, not for every game, but something that comes in handy from time to time.
The....Maybe?
Covert Action (T1): So the thing to remember is that rigging elections is almost 100% already (I can honestly remember 1 time in my last 20 games I saw an election rig fail, I actually until that point thought it was 100%, so this is really about the coups.) That said, coups take a lot of spy management and they fail a lot, but if you consider the "free" cost of the spy, and you just coup as much as possible with your cheap Tier 1 spies....this bonus might actually be good, I honestly don't know.
My Changes
And now the ever so controversial changes. My goal is to focus on the bad tenants while at the same time ensuring Freedom has enough science and military benefits to be competitive.
- Avante Garde (T1): Boredom needs reduced by 20%. All specialists generate +1
So this is a slight tweak, but we we are doing is increasing the core specialist boost, which then is further magnified by all of the GP boosts. So this now better rewards players who are milking all of those other bonuses, as opposed to just getting a weak bonus to add on top.
- Civil Society (T1): Removed
Rationalism already gives us this kind of bonus. I think urbanization is the more interesting of the two, and so we will focus on making that policy good.
- Urbanization (T1): Farms, Camps, Plantations, Villages, and Unique Improvements gain +4 food and +2 gold.
The food bonus was already pretty solid, we just need another good yield to round us off here. Also its time to give villages some love, I rarely want to work them at this point in the game.
- Universal Suffrage (T2 -> T1)
The bonus is fine if it comes a little earlier, and that fills the hole left by the civil society removal. Now giving us a T2 tenant to play with.
- Arsenal of Democracy (T2): When you gift a unit to a CS, you gain gold equal to half of its purchase cost. When you liberate a CS, the CS is healed to full and immediately gains all defensive buildings. You gain triple the normal influence bonus, and all of your units gain +15 XP.
I liked PADs liberation concepts so I took some pages from it here. So now we are focusing the arsenal on CS protection. We now make it easier to do that through cheaper unit gifting, and greater rewards to liberate the CS taken by autocratic players who love to snipe everything late game.
- New Deal (T2): Landmarks and GPTI gain +7 to the appropriate yield, and +4 tourism.
New Deal isn't terrible it just needs a little bit, and this gives us a T2 tourism booster to keep us competitive.
- Their Finest Hour (T2): +33% City Strength to all cities and allied CS. Can use B17 bombers (unit upgraded to be cooler).
Freedom players tend to have real trouble maintaining CS in the late game against the superior militaries of order and autocracy, so this helps the "turtle strategy" of freedom players who wants to duck in their cities for protection. I don't know what to do with the B17 at the moment so I'll leave that open for others. Combine this with the new Arsenal of Democracy for the ultimate in CS protection.
- Transnationalism (T2): Immediately gain franchises in 3 random cities once your Corporation is obtained. (the rest the same) 15% random chance, +25% franchise max, +2 culture from corp offices
Just a bump here to give it a little bit of Order's "immediate" franchise advantage. This gives it a solid start, and then it can grow as before.
- Alliance for Progress (New T2): Gain 10 influence with all known CS when you expend a GP. 10% of global GPT
is converted into 
Simple but oh so powerful, this lets us use the raw economic engine of freedom for science benefits, plugging the science gap that freedom was missing. We keep the influence bonus mostly as a ribbon
I will put these ideas in the OP without the explanation for a nice clean list.
. Specialists require 2 less 
from corporation offices.
Influence with all City-States, and 40
in a city is converted into 
RCS of allied cities is new code and it is such a microscopic, fringe benefit, I can't imagine why this change would be worth it.
CS bonus and only 25 less HP, but Arsenals give indirect fire and +1 range, while Military bases give other bonuses that don't actually directly help the city defend itself afterwards. What is a newly liberated city supposed to do with +25%
to planes?
