Uninstalling provides an additional barrier to returning. I mentioned that I expect users that didn't uninstall to return at a higher rate than users that did.

It's also not just about the price. A new benefit to having an Amex platinum card is $200 per year in Uber ride credits. I do not plan to return to Uber to use the credits. In fact, this is making me seriously consider not renewing that card when the annual fee comes up in a few months. I don't want Uber getting money from me, even indirectly.
