Eh, the more mindshare these people think they have the more crazy they become. Pre-2018 Elon was more focused on the companies, although he still made mistakes (Taking TSLA private tweet, borderline self-dealing with the SolarCity acquisition). The cave rescue fiasco and how he was sleeping on the floor of the factory during the 2018 Model 3 Ramp[0] (which also supposedly had Tesla a month away from bankruptcy[0]) must have triggered something, perhaps he'd already done the hard work and wanted to celebrate by increasing his fame/clout and by eventually purchasing his favorite social media platform.
