In a free society everyone should be for the protection of free speech. Note that this does not mean unmitigated slinging of fecal matter. It does, however, mean that platforms with significant reach should not be engaged in explicitly favoring one side or another. They need to enabled open and "color blind" discussion. And, yes, while moderation is necessary even in places like HN, it cannot, should not, be ideological. That's how you end-up with China, North Korea, Iran, etc.
Cue arguments about the first amendment only being applicable to government. That isn't what this is about. At all.
Imagine an extreme case where all social media outlets, news stations, newspapers and even universities are controlled by, say, the Chinese Communist Party or some other extreme. Yes, a crazy out-there hypothetical. Sometimes exaggeration is able to lend clarity that is hard to convey in other ways.
Well, that's the kind of thing we have had for years now. Don't believe me? Kindly present a list of right wing, left wing and independents who have been banned from places like Twitter and Facebook. One side of that list will be almost empty. And that, precisely, is the problem Elon wants to solve. He isn't interested in tilting it in the opposite direction. He wants that list, when it comes to Twitter, to be equitable and, more than likely, as small as absolutely necessary.
What is wrong with that? Why the hatred?
