I don't think it was impetuous. I think he did this all on purpose and planned on using his usual tactics of improvisational manipulation and grandstanding to get what he wanted, whether it was Twitter at a cheap price, manipulating the Twitter stock price to make a quick buck off of his stock purchase, liquidate some of his Tesla stock, seed further discontent on Twitter, spur on rabble around bots (despite knowing full well that Tesla and himself have benefited from Twitter bots and potentially even controlled them), drone on about free speech in some sort of libertarian political play, or whatever else. And it has all failed. Now, he's just gonna let his dirty lawyers figure some way out of it all and move on to the next scam.
