Yeah I'd agree with that.
I thought it was a bad idea him buying it, both for him and people generally who use it. It was a very poor decision financially, him having paid at least 3x what Twitter was actually worth based on their loss-making history.
I also happen to think as a business propostion it is a poisoned chalice. It is a pretty toxic place to be on for too long, and definitely very left leaning - but I can also see that advertisers aren't going to touch anything that approaches a "maybe the right have a point about XYZ" forum, so I can see why it would be the way it was.
Never in my wildest dreams would I think that Musk would torpedo it the way he has. I could have easily believed that people would be turned off by his involvement with it, but I imagined he would navigate that by taking a more backseat "grand plan" role. As it is he's alienating everyone and all of his monetisation ideas sound like throwing crap against the wall to see what might stick. Truly bizarre.
He's not doing his cultivated image of genius ahead of his time any favours at all with his antics, if anything I'd say it is probably suggesting to people that his previous successes have been fortuitous. Either way - not good for Tesla.
