Who is the "he" you're referring to, Musk or the OP?
Regardless, if you believe that the govt being involved in a conspiracy with a private company to deny people freedom of speech is not outside of legal bounds, then you and I have very different ideas about what it means to be free.
IF the Tweeter had done that to everyone, for some reason other than differences in political ideology, and without govt involvement, then you could get me on board with the argument that as a private company, they can do what they want.
But what they did with total involvement by the govt was nothing short of election interference at the highest and most egregious level.
The access issue that you seem focused on is irrelevant in this case, imo. Because it's clear that all the govt had to do (and they did it, no denying that) is tell Tweeter which posts and accounts to go after. That is about as un-American as it gets. They didn't need some magical access to Tweeter data to pull this off. Assuming of course, that by access you're talking about data. If by access you mean to people, then look no further than the trove of ex-govt stooges that Tweeter hired, who when they did work for the govt were mostly in the field of intelligence. (an oxymoron for sure!) Why did the Tweeter need so many spies with fresh govt connections working for it?
