I guess there was probably a big exodus of people after the IPO. All those employees were locked into their positions due to 90 day exercise windows. Once the stock was liquid they had no reason to stay anymore. Then there was the whole “Uber is an immoral company” shtick that gave employees yet another reason to leave (to go work for more upstanding companies like Facebook, I’m sure).
Yeah, it’s no surprise Uber is having trouble. Demoralize your work force, make enemies of regulators and drivers, experience a multi-year global pandemic... none of these things are auspicious signs on their own. Taken together, it’s hard to imagine that Uber hasn’t peaked.
