You must have been asleep during that entire situation. The Twitter board did not want to accept his offer, they elected to adopt a poison pill... it wasn't until they got threatened with shareholder lawsuits that they accepted it. Musk's team openly talked about how the due diligence wasn't adding up (users vs bots)...
"in a show of petty vindictiveness starts firing people" is a wild opinion, dude took over a fire drill of a place that was lighting money on fire... let me re-frame it for you. In this situation, mid 90s, you'd be posting the same thing about Steve showing back up at Apple... going WTF is happening here, laying off people left and right, and killing product lines... desperate times call for desperate measures (ones that Apple went through before as well)
"Claims some sort of freedom of expression crusade but it seems to be mostly allowing disinformation and hate go rampant". yeah you have no proof of that... but keep spouting that BS. The Twitter files also have shown how much government involvement was happening, and it isn't pretty. Community notes are what every other social media platform should be adopting
