My dude, you said you're not that into Warhammer. Maybe you don't have your finger on the beating pulse of the general fan community
Anyhow, stuff is always changed because of "out of universe reasons". New editions are released due to a need to update the rules, and / or a need to sell more / better / newer stuff. It's a business first, on top of a fictional universe. I don't give two hoots that you - someone who isn't even apparently a fan - doesn't care for female Space Marines. That doesn't matter to me. What's more interesting is apparently how much you know about one specific thing in Warhammer 40k despite not being that into it.
EDIT
I missed your complaints about WotC "going woke". Negative stats for racial typing is outmoded design, and new editions of DnD are stronger for not having it. Assuming a classic stat-rolling experience, you're already at the mercy of the dice for the rolls you get. Having a -2 penalty on top of that for one or more stats just really pidgeonholes what you can do with the character.
Also, some races were genuinely just horribly balanced. 3.5ed, you'd never pick an orc unless you were going Barb, basically. Not without heading into extreme munchkin territory. Even half-orcs were better for the Fighter class.
I've got to say, props for providing the thread with some examples of making discussion around a game political, even if it wasn't the kind of politics the OP may have been referencing!
I'm not that worried about negative racial modifiers going away. An elf getting +2 dex though is also a no no.
If female space marines sell them more product by all means go ahead do it.
In D&D they're also complain ing about Orcs and the evil humanoids being all mean an unfair though.
Looks at Warhammer Orks and essentially race wars.
