Parody absolutely does fall under speech, not only being legal and considered valuable for political discourse even in places with strong restrictions on other types of speech but also having explicit case law protecting it under the First Amendment. (Copyright law is a different matter, but nobody is selling their "Elon Musk" accounts). Of course, private websites are perfectly entitled to ban it, just as they were entitled to ban other stuff (there are reasonable grounds for thinking some unlabelled parody may be problematic, but there's a school of thought that racial hatred might actually be worse!). But it's impossible for Elon to credibly masquerade as a "free speech absolutist" whilst simply changing the guidelines to focus bans on stuff that annoys him more than the stuff that used to be banned. I'm sure some other people were banned for unlabelled parodying accounts under the new rule too, but they're busy stopping people using labels as obvious as "Elon Musk (Parody)" too...
