Twitter isn't "an important part of society largely subsumed by corporations", Twitter is a corporation and has been one from the start, but more importantly nobody is forced to use it. People use it because they like it, but frankly, in my opinion and in the opinion of pretty much everyone I know, twitter is mostly crap by a huge margin.

>nobody is forced to use it

Social conformity is far more subtly persuasive than outright violence in this day and age.

"Choosing" to opt out of corporate ownership is equivalent to a de facto excommunication from society.

Not using twitter isn't an excommunication from society, that's absurd hyperbole that might be a sign you're living in a bubble. I don't use twitter, most people I know don't use it, I'm willing to bet most people on this forum don't use it, which is all totally anecdotal, but the effect size is massive.

Obviously not, which is why I said "opt[ing] out of corporate ownership" which includes but is not limited to Twitter, Facebook, Google, Verizon, AT&T, Comcast, Microsoft, Apple, Elsevier, etc.
