Bunch of random engineers in this thread talking about business when they have no clue how companies are run.

Yes- Uber was making loss before. But their ridership was growing and they were giving incentives on the supply side (drivers) to bring more players in. Thus it made sense to continue investing in headcount to grow. Now, though, everything is disrupted. It doesn't matter that they are losing money slower - if the outlook of the business is weak then they cut costs and reduce headcount.
