Honestly I feel like that killed Twitter more than many other changes.
People tell me "there's no way he (musk) would intentionally crash his own company - it makes no sense - "he's just terribly bad at business!"
But is he really THAT bad? In what world could these changes be made in which he's actively trying to improve the company? If nothing else, seeing the negative backlash, bad publicity and dropping number of users wouldn't any sound minded business owner at least temporarily undo some of these changes?
With any business, if you make a change that causes you to lose customers and get bad publicity.. don't you try to mitigate the damage done? Who goes balls to the wall on obviously bad decisions?
