Right, you have to have a forgiving policy for banning people. The general rule for a social media platform should be freedom for the exchange of ideas, but there are reasons you have exceptions to the rule. Most people who spout BS don't inspire grand-scale harassment against victims of the most heinous tragedy you can imagine. This was a good battle to pick, and there is a reason Elon was resistant to re-admitting him. But Musk now knows for sure he's not winning the left back, so the best $-making idea is to appeal to right-wing nutjobs.
It's funny that Musk is talking out of two sides of his mouth on this...we aspire to be the free speech platform but only if a majority vote in favor of it. That's not free speech. That's speech governed by the mob.
