Yes. A handful of megacorps acting together (and they all act together generally) can take away your property by banning you, which makes it impossible to have a normal career in fields as diverse as academia, creative media, journalism, tech, and many others. If you're running a small business and trying to promote it, being banned from social media is a huge hit as well.
They already have taken away your liberty to speak your mind in the common public square of our society - social media - because you know they'll ban you if you say any of a wide variety of things, leading to the consequences described above.
The common public square is just that - paid for and maintained with public money.
Trump doesn’t seem to have any issue getting his message out or getting people to come to his rallies.
Before the internet existed, the entire civil rights movement was organized by leaders going to churches - even though the locations were actively being bombed, leaders were being arrested, water hosed, lynched, bitten by police dogs, etc.
Cry me a river that some conservatives can’t post on Twitter.
