Meta will not stop short of government action and I wouldn't be surprised at all if this is happening at the request of that government in the first place. Zuckerberg may have some excuse (say, they showed him a documentary about Jack Ma) but he definitely either folded or just straight up decided to comply in advance.
The world exists in shades of grey my friend..
So walking away would allow the former-employees to have a clear conscience, in full knowledge that the evil will continue exactly the same without them?
This is a somewhat exotic philosophical position you are staking out here
So they know nothing will change regardless of what they do and yet they willingly continue to sell their time and skills to said evil organisation?
Interesting.
You wouldn't be surprised if the incumbent candidate requested that Meta platform and systematically encourage voting for their rightwing opponent? What do you think happened here?
And as for me, I want people with morals to stick around and try to influence things in a positive direction. It's so easy to get on one's high horse and say "then go elsewhere", but everyone acting like that is a short path to a worse world. Tend the gardens you are in while you can, but I don't blame anyone who just can't carry that torch day-in, day-out.
So we should rather want these people to stay on for as long as possible, and make it hard for Meta to pull off such shit.
