Yeah, I still can't figure out what sort of mentality makes that seem like a good idea.

For Musk there's at least a chance of some sort of thought process going on there. Narcissistic people tend to think that everyone else is just like them (although maybe a lesser version of themselves.) Musk has had a very serious addiction to Twitter for a long time, therefore everyone has a very serious addiction to Twitter, therefore we can charge people a ton of money for their Twitter and since they can't leave they'll have to pay for it. And legal repercussions? Why, he's never seen those in his life!

Maybe spez is the same, just with a bunch of alt accounts so that he can post in /r/jailbait or whatever. I can see why he might want to turn reddit into 9gag if that's all he's ever used it for himself and isn't capable of understanding the concept of other people having different uses for it.

But at some point he must notice that it's not been going well? Right?

i mean, depending on what do you want to do, this might be a good idea. their motivations remain unknown, maybe they wanted to burn the place to the ground before an ipo, you never know
