>>maintain their fiefdoms of extrajudicial decisions about what is or isn't considered protected speech
Where do they do that?
My understanding of U.S.A. First amendment is that government won't infringe on your right of free speech. It doesn't say you can come into my home, workplace, store, or website and yell what you want on my property.
There's nothing "Extrajudicial" about it and it's not "Protected speech". It's just a business owner saying "you can say whatever you want, but not necessarily in my home, on a platform I built and pay for".
I think we've gone weird somewhere if we think Facebook == Public Square on any level. It's just somebody's storefront (and insert cliches about who / what is the product :)
In some ways, I am hoping tech giants do MORE weird policies / bans / things, so hopefully general population sees it as a private proprietary closed property / platform that it is, not a friendly public gathering spot we somehow take it for. But I still don't think they are doing anything illegal/extrajudicial... it seems people feel they have strange rights or ownership on Facebook or Twitter, have some investment in property, treat it almost as a mix of paid-for condo and public space (depending on what they need to assert at the moment)... and none of that is the case. At best, you are walking in a Mall, and if you start yelling obscenities, pontificating, or even start advertising for different shops etc, the mall security guard will escort you out, as is legal and proper. It's not government infringing your constitutionally protect free speech, it's not extrajudicial, even if you don't like it and really really wanted to yell obscenities or market your business or promote your personal point of view in the mall.
