The release of the previous management's internal communications showed the liberal and comfortable application of euphemism, justification after the fact, and technical deniability in upper leadership.
Twitter showing outage not over evidence that the culture of banning and de-amplifying both users and public interest topics without agency or notification, condemning by decision of a secret, unauditable council under influence of the federal government and corporations, and doing so under the tack of keeping their CEO in the dark shows how carefully calculated their appearance was. Remember, they lost their canary.
I don't think Elon Musk is much if any better. I also can't say that Twitter is any worse. Speech was being chilled and controlled before, and unless your definition of "free speech" is "being free from what offends me or is counter to my opinions and beliefs", it's more likely the hypocrisy you worry about is nothing more than actually being able to draw a line between an action and its cause and a target you can confidently level a finger at.
People will adjust as they ever have. However, the ones who interact now will be the influencers of what Twitter becomes. That is what matters, not any confused and petty logic that our leaders should all be infallible and godlike.
We all know why these rules are being made, that Elon musk's feelings were hurt and he's lashing out, but Twitter is pretending that it's for some consistent rule. Transparency would be for twitter to say straight up that it's against the rules to say things Elon doesn't like
