I feel like we're talking in circles here: your "far better app compatibility" is a phone useful for nothing, and if the user chooses to install Google Play then they have a usable phone at the cost of their privacy. ¯\_(ツ)_/¯

The goal of /e/OS is to provide a more-private degoogled OS that is usable out of the box by normal people: an app store, maps, etc.

This whole conversation reminds me of talking to Slackware users in the early 2000s: "I don't understand what you mean, it's compatible with everything you just have to recompile it. It's 100% secure, it comes with zero services running."
