Musk takes over Twitter and faces social media crash course

Twitter's newly minted owner, the self-described “free speech absolutist” Elon Musk, is about to get a crash course on global content moderation.  

He also posted a conciliatory note to wary advertisers, assuring them he won't allow Twitter to devolve into a “free-for-all hellscape.” 

The problem is, not even the world's richest man can have it both ways.
