The difference, as I mentioned upthread, is that Twitter does this now but also has broad rules that do NOT allow speech on the platform that Elon would like to enable by his original assertion.evnow : Musk said they will follow the local laws.
Response : Its not scalable.
evnow : Twitter already does this using automation.
It’s much simpler to implement “you can’t do all of these things that aren’t technically illegal, regardless of where you live, but we deem to be inappropriate” vs “we are going to allow all speech that is legal specific to the area in which the tweet was written or will be read.” The latter is a great deal more effort.
