Well the key point is, Elon had the chance to examine all of Twitter's supposed lies before signing on the dotted line. He chose not to. So all his arguments about bot numbers and mDAU and whatever else are entirely irrelevant. Nobody cares. They might have been made up, they might have been lies. Doesn't matter at all. Because he had the chance to dispute those figures but was more interested in posting memes on Twitter than doing actual due diligence.
If the fact that Twitter was already running themselves into the ground was apparent to a random myBB poster like you, surely it would have been clearly obvious to Elon, and then confirmed via the copious amounts of research he would have put in, before deciding to commit forty-four billion united states dollars of actual money to buying this dumpster fire? Isn't he supposed to be the most brilliant businessman in the world? Surely someone of his business acumen wouldn't do something so idiotic as that?
