What about private industry acting as a government, with similar power.
With that said, they are only doing what they know the masses want. So in a way, they're just doing the people's bidding. If Google thought the majority wanted Parler and hate speech, they'd certainly have kept it up.
I actually did think it was cool! However, if there were any right wing folks there, naturally they kept quiet.
Also, there are a huge number of conservatives and moderates using Facebook. The main point I’m trying to make is that it is misguided to believe that these companies do not have their very own conscience / worldview / quite strongly held political values.
