I was a heavy Uber user for years. I understand why they would like to collect additional GPS related information, but their decision to take away my choice and force me into "no GPS at all" or "GPS even when I'm not using the app" was a clear "f**k you" to its customers.
I contacted their customer service and let them know why I was leaving their platform and switched to Lyft.
The rest of the news about the organization in the months since may not have been enough for me to stop using the service, but it has reinforced my choice (i.e. if they reversed their position on GPS, I don't know if I would switch back right now)
