Don't be disingenuous; the incongruity is over the previously stated commitment to maximally free speech. Twitter by Musk (tm) absolutely has the right to throw people off, set narrow content policies, and so on, just as was true under previous management. But equally, others have the right to point at the hypocrisy and say 'ha ha', because Musk swore up and down that he was gonna Be Different (tm).
As expected; by a private platform.
