I think we should be pretty clear about a few things regarding this Elon Musk / Twitter situation.
First, being a publicly traded company comes with significantly more oversight and regulations to follow i.e. more public accountability. That doesn't mean all publicly traded companies are better than privately traded companies, or vice versa. However, if people are genuinely concerned about Twitter's content moderation strategy and accountability, privatization does nothing to alleviate those concerns. Instead you transfer the onus of responsibility and accountability onto fewer individuals with less legal accountability obligations. It's befuddling that people are confident this is somehow a good thing for Free Speech as it is highly, highly debatable.
Second, he has stated that his position is if something posted online is "in a gray area, it should probably be left." He is not saying "F it and say whatever the F you want." That's what morons like this Mike The Mad Scientist seem to think this all means. Somebody is still going to have to define that gray area is and moderate that gray area because we all know that you can't literally be allowed to say whatever you want, whenever you want, wherever you want. That is not and has not never been what Free Speech is.
I don't have a dog in the race as I'm not a huge Twitter user most days, but people have developed some whacky narratives with all this.
