It's a good line, but Cruz was more clearly talking for the camera then for information from Dorsey. I do like that he acknowledged that Zuckerburg clearly realized that maybe social media in it's current form is less "a wonderful tool that allows us to talk and share with people around the world" and more of a polarized hate machine in the center of a dopamine fueled feedback loop, and Zuck's started slowly fumbling around trying to find the off switch (whereas Dorsey clearly got pulled into the gears of his machine at some point....perhaps that long, unkempt beard was a bad choice).
Cycling back to Cruz though, I think his desire for unrestricted free speech online is a solution in search of a problem. The problem with twitter isn't that conservatives are being muzzled, it's that whole polarized hate machine thing, and the best case senario if Cruz gets what he wants is that the right manages to get our own hate machine running just as well as the one the left has.....which I can't really see as any sort of improvement. What needs to happen is something that discourages the kind of behavior, that encourages people to realize that bullying people into silence doesn't make them submit, it only sows resentment and hostility going forward. Unfortunately, as Wesley Snipes once said (sorta), "Yeah, but you can't take away people's right to be assholes!".
The problem isn't that New York Post isn't able to post on twitter while Keith Olbermann can, the problem isn't even that Olbermann is still on twitter in the first place. The problem is people listen to Olbermann in the first place even though it's blindingly obvious they shouldn't, and there's no mechanism to stop them from doing so....at least, not without creating other, far worse problems.
