Musk's lawyers justifiably characterized this lawsuit as a "disjointed laundry list of — often irrelevant — grievances," and Judge Breyer agrees. While Musk may have enriched himself as a result of the buyout, even though the company has since lost half its value, Heresniak didn't lose any money from it. There was no proof the plaintiff actually lost any cash over this.
Though company acquisitions are typically mutually beneficial agreements for both buyers and sellers, Musk's decision to publicly bid on the company — and then abruptly pull out of the deal — was not a typical acquisition. Musk did eventually pay the $44B offer that he went to court over, but that doesn't take away the dip in share prices that occurred between the day he first announced his bid and the day the deal went through.
