Is it? I always thought the uttermost definition of "Free speech" is that you have the right to have a stupid, ugly or wrong opinion? And as long as you don't violate any ToS (e.g. Hackernews, as a private enterprise or organization) or laws (kill XYZ type of people) you are within the rights of "free speech".
Musk's version of "free speech" should be in quotations. Twitter was banning accounts, even Paul Graham's, for saying "This is the last straw. I give up. You can find a link to my new Mastodon profile on my site.”
You can only have a stupid, ugly or wrong opinion so long as Musk shares it. Luckily Musk is uniquely dumb, so that covers most awful takes you can have, perhaps giving the perception of free speech.
