That's a terrible premise to start a conversation on HN. Let's not use extreme concepts invented by ideologues + controversial figures being petty as the basis for thought experiments.
Stochastic terrorism may be an extreme concept invented by ideologues, but the fact remains that if you have a big platform and you criticize someone harshly, that might cause crazies in your audience to go after them. So as a society we should figure out what is and isn't acceptable behavior here, and invent rules to apply universally and impartially.
You can't censor your way out of this problem regardless. People will still post Elon's flights details elsewhere.
Censorship is almost always counter-productive and every time it fails it just escalates. Eventually we'll be doing night raids on people's homes over tweets like the UK.
The costs are far too high for very little benefit. Just look at the moral and cultural compromises taken by the US/Canada/UK in Afghanistan/Iraq/globally to crush Islamic terrorism by force. It generated as many problems as it helped, at a very high cost of tons of freedoms for the western public (not just people in the middle east). Now we're on Part 2 of "compromise freedoms for the greater good". No thanks.
