1. In one hand, the rolling back of how DEI has/was implemented I think can be a good thing. I think lots of people, myself included, believe that it "went off the rails", but most importantly, I think it ended up being counterproductive to its end goals. Nearly everyone I know who wasn't part of the DEI cottage industry came to view many/most of these programs with cynicism, even if they weren't vocal about it.
2. Don't mistake the validity of number one for thinking that this is just pure and unadulterated pandering to the incoming administration. Meta would sacrifice small babies if they thought it would make them more money in the long run.
The reason I believe so strongly about number 2 is what happened with their content guidelines changes. I'm gay, and I'm actually fine with people calling me insane. But I also better be able to call lots of religious practices based around some invisible sky fairy insane too. The fact that the guidelines specifically called out "it's OK to call gay and transgender people mentally ill", and only those groups, is grossly despicable, and clearly shows Zuckerberg is just taint licking his new overlords.
And to people who still work at Meta, I also think that's fine - we all need a paycheck. But please don't try to convince yourself or anyone else that you're doing it for anything but the money. I'm so sick of these tech companies talking about their lofty goals (and honestly, have been for a while long before Trump) when it's so abundantly clear it's just about making money. And again, I think that's fine to only be about money - it's a business after all. Just don't pretend you're doing some sort of societal good.
