I don’t give a flying fuck about Facebook, Google, Apple, etc. I don’t care about whether it’s a good thing, a bad thing, or an indifferent thing. If you want to discuss these things, I can point you to several threads that seem to want to discuss this, but that I for the life of me can’t figure out the actual question they want answered.
My stance is that Twitter can indeed legally boot you for whatever arbitrary reason they come up with (excepting as noted in the title, and it’s not a given that they can’t do it for those reasons). They can do so consistently, or inconsistently, and can revoke the suspension for the same reasons, or lack of reasons, if they so choose.
There are no 1st amendment issues, as it is a private enterprise. There are no free expression issues as the number of people on Twitter has no relevance to the audience size some individual might have. Your typical Twitter user has around 20 entities following them and follows around 75 entities. They also post two tweets a month and retweet something once per month. This very post on this very message board will be seen by far more people than your typical tweet. The median tweet has 0 likes and 0 retweets. The barrier for entry for a competing platform is so low as to be almost non-existent.
What Twitter does have is some popular entities. Just like everywhere else, on Twitter popular entities are popular. They gather a large audience as a result of being popular, not as a result of which platforms they choose. That’s what the word popular means, after all. Popular Twitter users will gain popularity on the next quick-blurb social media platform of their choosing. Just like popular Vine posters are now popular TikTok posters. Banning a popular entity hurts Twitter, as it reduces potential user activity, but it’s still their right to do so.
You, Donald Trump, Barack Obama, and myself don’t get an audience by default. We either grow one, or we don’t, on Twitter, or elsewhere. Twitter doesn’t owe any of us anything and we can build our own internet platform to shout at the world for the cost of one Five Guys burger a month.
So yes, they can boot you for any reason.
