Arsenal of Democracy is a second-level tenet and is very powerful in itself. So if you are first to unlock Freedom, it's the next policy. Not much commitment needed.
Also, they're "tenets", not "tenants".
Tenets, sorry, just a word for me (not a native English speaker).
But AoD takes commitment because if I am not remembering that one totally wrong, you get extra influence by giving units to them. I rarely have extra units to give away. Some units not worth to upgrade, yes, but otherwise not. Sure I can build some cheap units to give away, but that takes commitment, by building them or you can give them the units that you got from military CS, but that is not so many.
Perhaps we play differently you and I, I rarely have time to build units just for fun, my cities have other things to build. But that's just it, you apparently like to spend that time to build those extra units to give away, you are committed
