I'd take a candidate who fights for a view I disagree with over one who hedges to please everyone (Strong opinions weakly held, but willing to change their mind if/when the data tells a different story)
Uber burning money on opex and Uber investing in Uber's future (through Lime) are two very different ways to spend money. Don't expect Uber to stop spending money, it'll simply do that differently.
There is a misconception that Uber loses money on every ride. If you look at their SEC filing, it's not how they actually work (I won't have time to do that search for you now but will try to edit my post later). TL;DR of their SEC filings:
They're not losing money on every ride, they just have such a high baseline of fixed costs (payroll being one) that they haven't started being profitable. Doing fewer rides right now is actually killing their profitability.
