I can't speak for jngreenlee, but a lot of people are uncomfortable with Uber's business tactics and ethics. Their HR team allegedly sidestepped one employee's very serious sexual harassment complaints, they've allegedly been complicit in using stolen LiDAR IP, along with a whole host of other shady things they've done in competition with Lyft.
Howdy fellow Austinite, you somehow managed to speak for me anyways! These are additional reasons for me to have some resistance switching, even if Lyft had failed me in some way (they haven't).
Add to it that they want to "always know my location", etc
