If Twitter wants control over what's published on their site, then they give up their rights (their 'free harbor'-alike protections) to not be held responsible for the content they censor and let through.

Twitter et al. are where modern speech happens. They pushed themselves into this position, and thus upholding the human right to free speech also falls upon them.

So long as Twitter is not shut down, then perhaps some government oversight (to the limit of holding Twitter responsible for what and who they censor) is appropriate.

Free speech, in this case, trumps my intense dislike of our current administration.
