All politics should not be acceptable in some sense. As in it's fine to discuss your views with colleagues over lunch. It's fine to express concerns privately over appropriate channels.

If you disagree with the contracts your company takes on you can always quit. There is no need to make your coworkers feel threatened for just doing their job.

As absurd as your comment may seem, I honestly would genuinely prefer this over the current approach. As you said, it's currently pretty much a guessing game as to what left-leaning opinions you need to pretend to support in order to not get cancelled or ostracized. It's so stupid... if Google truly just cares about the bottom line, why play this idiotic game where you need to get all huffy and puffy about individual workers opinions? Why not just dispense with the whole façade of pretending to care about left-wing causes? Like at this point the fervent supporters of left-wing ideology HAVE to sense the "how do you do fellow kids" energy coming off of these major corporations.
