Also, we're talking about tech workers who get stock compensation, right? They literally own (part of) the company.
What if you do like them and so you want more of them? Maintaining culture doesn't happen on its own.
Note everyone's job is making hiring decisions, most companies don't have central hiring like Google does (and do they really?).
NO GOSSIP
NO POLITICS
YOU WERE NOT HIRED TO HAVE OPINIONS OF YOU OWN
JUST CODE
See what happens if you spend more than any trivial time on the job doing something else other than what you were hired for!
The Basecamp policy is now that you can't discuss politics (or anything controversial) on any company platform, including e.g. in the break room, on the discord chat or whatever on your commute, out of office hours, etc. And they are officially removing any feedback mechanisms from company structures, figuratively salting the earth to prevent anyone discussing anything.
Obviously everyone could move to a platform in the cloud for discussions, but the writing is on the wall.
While this may well be a gross violation of labour laws, US employee rights are so weak it doesn't matter: say anything and you're canned.
These are questions for people at work whose job description involves hiring, payroll, and the corporate charter. These aren't collective questions to be debated and answered by employees whose jobs are completely unrelated. If, for example, you are hired to be a programmer, then your job is to program - that's all. Its not up to you to decide what the company's mission should be, or, "whose problems we are trying to solve". While a programmer is debating these philosophical and political questions with other programmers, they aren't doing the job they were hired to do - program. Certainly if the ownership of a company decides that they want to hire people to not only program, but also opine on their political and moral beliefs, that is their right. But is also their right to decide they don't want to pay people they hire to opine and debate during work hours on issues that have no direct relevance to the job they were hired to do. Just as it is your right to refuse to accept a job at a company that hires you to exclusively do a job without bringing your political baggage into the workplace.
