Yes, progressives are against monopolies UNLESS it benefits them.
I'm well beyond this basic bitch Lolbert argument about private companies having the right to refuse business to people. If the state uses corporations (incorporation was created by the state, BTW) to cancel individuals or groups, those businesses are state actors, period. A majority of social media outlets are a part of the state propaganda machine.
