I'm quite happy with taking the good with the bad. Apple may be forced to open up and allow other app storefronts, and the downside is a reasonable concern. The upside though, is considerable: A proper open-source and entirely free app store that is treated like a First-class citizen.

I don't have Google Services installed, and rely entirely on F-Droid, with no extra repositories enabled. I feel my personal information is much less likely to leave my device installing any app through F-Droid compared to any app on Apple's store. Despite how locked down the App store is, I still trust it less than a third-party store.

I believe Apple users end up with all the downside (limits on which apps can be built and easily distributed) and none of the upside (an app store with which I trust every single application on).
