I don't necessarily agree with the parent's implication, but the point they are making is that a lot of people defend some speech-controlling-but-not-illegal practices of social media sites using the exact same reasoning you are using in your post, and there was a lot of hype around Elon potentially being an opponent of that.

Even discounting this incident, finding people and organizations that Elon has banned from Twitter isn't even that hard. I find it very difficult to believe that people who claim that Elon is some sort of free speech absolutist actually believe what they say.
