>They're a private company, they can do what they want, they're not a public space in which you can talk freely. And you can still talk IRL to whoever you want silly...

Except you can't, can you? Not with corona. You're not allowed to gather in public spaces, and you're allowed to gather in large parties in your home either. So which place exactly do you have left for freely sharing thoughts and ideas?
Your government has already implemented a work-around to stop free speech happening IRL, and "muh private companies" are denying it online.

So what are you going to do?
