> The Android userspace is actual garbage. It's very heavy and the UI paradigm means you're sitting staring at blank screens while you wait for things to load or switch or whatever and things are constantly getting evicted from memory and forced to restart (or crash sometimes.) It made some dubious amount of sense when phones had 512mb of ram but once you hit 1Gb it just became this over complicated mess that adds nothing but pain.
Compared to your average desktop computer, Android at least tries to use SELinux, and by-app unix user partitions. Systemd/Linux "Flatpak app" and "snap app" security by comparison is awful.
I think that Termux, (once you get past Zygote forking) to be reasonably fast and responsive, and it runs on almost barebones Android/Linux fine. So I don't think it's fundamentally related to the Android userspace platform as well.
> Android's app ecosystem isn't much better, it's mostly converging with iOS as a tool for corporations to deploy their telemetry into your life rather than a platform for running useful community maintained software.
I think we all need more libre software in our lives. Or at the bare minimum, more things like F-Droid; not ideal since the base OS is still somewhat locked, but a start.
