He's proven himself thin skinned, egotistical, and capricious, and is easy to provoke into vindictive & retributive actions even if not in his best interests.
I think a big part of why he bought twitter was a sense of grievance, basically that the wrong people were getting positive attention, that people were being mean to and making fun of him and his friends & allies. He wanted to restructure the mechanics and incentives of the platform to better support the people and outcomes he values.
I'm not sure whether he succeeded by these terms either, it's still too early to tell I think. But I do think it's an important factor in evaluating whether he succeeded in what he set out to do when buying twitter.
And from that perspective "make it good or (let it) die trying" may be an acceptable compromise. He doesn't get the musk-adoration platform he wants, but at least there is no longer the musk-ridicule platform he perceived it to be.
