None of that matters, because Elon can’t claim to be mislead by a figure that didn’t exist when he made his offer. Whatever he expected it to be has nothing to do with twitter saying it is 5% in May.
I dont think its fair to expect Elon, or anyone, to have done due diligence beforehand in a situation when it would have been impossible to collect the relevant info without some shady tactics. Unless you mean his team should have employed shady tactics to gather that info.?
Sure he may be employing this as a stalling tactic, but there’s no obligation for him to treat the Twitter folks with kid glove either. This is what high stakes negotiations are about.
