I tried one distro and now the other distros confuse and scare me.

What about Apple? From my limited knowledge their ecosystem is even more locked down than Android’s.

What’s the upside of immutable distributions?

Running Switch games through emulators (primarily Yuzu since it is much more popular). Recently it had become almost exclusively about emulating Tears of the Kingdom.

On Android, it’s a bit complicated but you if you are experienced you can use termux and yt-dlp.

You can use yt-dlp from a desktop too.

For youtube on android you can use newpipe. It allows streaming as well as downloading.
