This tweet is so much funnier now. The whole backstory of Bioshock is that Andrew Ryan, the guy Musk is quoting here, started a city entirely to be a libertarian paradise, but the moment someone else was successful enough to compete with him he made himself a dictator, seized all their assets, and began killing anyone who challenged him. He’s a character defined by his hypocrisy, constantly giving speeches like this about freedom and people pursuing their ambitions without limitation, but throwing all of those beliefs away as soon as they start to inconvenience him.
You know, kind of like a billionaire who buys a social media site, calls himself a “free speech absolutist”, announces that “comedy is legal now”, then blocks or bans all of his critics and changes the rules to limit satire.
