Even before Musk, twitter amplified right-wing nonsense.

Now it's openly full of Nazis, because Musk unbanned them.

But you're right, it is a private company, and thus not subject to any definition of free speech.

Here's the thing. People do have free speech and can publicly say that they think the new twitter is a Nazi fulled dumpster fire run by a racist man-baby who got rich off of an Apartheid era emerald mine.
