This meme really needs to die. Uber did burn VC cash earlier on, especially in places w/ intense competition (e.g. vs Didi in China), but that's not an accurate portrayal of the company anymore. Uber has been a public company for like 3 years now, and they actually posted a profit on adjusted ebitda basis on Q3 last year (with a promise for a larger profit for Q4).
The Uber-is-cheaper thing isn't an accurate premise these days either. There have been numerous articles of people complaining about high airport trip fares due to the mismatch between demand and supply curves due to covid lockdowns/reopenings. There were also price hikes in two key markets (SF and LA) partly due to regulation.
