Not quite…they have certain liability protections granted by (act of) congress (the fabled “Section 230” of the Communications Decency Act), in return for which they are supposed to be generally content-neutral.
One of the things that astounds me the most is the fact there are so few Twitter-like or Facebook-like alternatives. I know there are one or two…sort of…but if all the conservative types caterwauling about not being treated fairly on these platforms actually got up and did something about it, maybe things would be different for them. What’s-his-name-gay-conservative-tech-guru-billionaire-guy from the GOP convention certainly has enough money and knowledge and experience and influence to move something forward, right?
Of course this would just drive even more echo-chamberism and tribalism and partisanship, but still…why haven’t there been any meaningful free market competitive responses?
