If Twitter shut down tomorrow and all it's users flocked to Gab or Parler or whatever network is said to currently be infested with racists, would they all star

If Twitter shut down tomorrow and all it's users flocked to Gab or Parler or whatever network is said to currently be infested with racists, would they all start posting racist tweets because now they're covered by moderation matching 1st amendment rights? No, that's not tenable. Same applies to Tor, it just needs more users. All "good" things have serious downsides. Free speech is good but if you defend it you'll no doubt at some point have to defend its use by a scumbag who using it in a scummy way - but the alternative is worse. Same could be said for democracy, presumption of innocence, habeas corpus or any other of the cornerstones of a liberal society - they have big downsides but the alternative is worse. Sadly, right now, we're living the worse alternative to having strong privacy because people don't see it's value so we'll have to make do with Tor.
