Sure, except Twitter doesn't have free speech. Twitter can and does issues bans for thing said, notably in the Kanye case, and when Elon banned the elonjet account.

It's either free speech absolutionism, or not free speech. If you claim you are for free speech in the moral sense of the word, you have to let everything be posted.

As soon as you start removing things, it becomes your version of controlled narrative. And there is nothing wrong with just that, because of course you want to minimize potential damage. But then you have to be responsible for the things you let slide.

So when Twitter allows right wing rhetoric, a.k.a conspiracy theories about Nancy pelocies husband, pushed by the CEO, or things like Fauci gain of function research, it's clearly a controlled narrative.
