Most everything works fine offline (think: airplane mode) - where it all goes to crap is when there is a connection but it’s slow, high latency, or losing packets.
In fact, sometimes it’s worth it to hit airplane mode if your connection is bad until after everything is running.
Exactly this. My personal hell recently has been the Audible app on iOS. I walk a lot and listen to audiobooks and often on my walks my cellular connection is not great, one bar or so. The Audible app had a redesign a year or two ago where it now instead of showing your library letting you play whatever you were listening to, it loads a home screen that tries to get you to buy more books, and you can’t do anything else until that finishes loading. But since it fails to load on a crappy connection, I usually end up killing the app, enabling airplane mode, and then re-opening the app. So stupid.
For reference, my audiobooks are stored locally, a network connection is not required to continue playing. Yet somehow they have hindered the main functionality of the app by what I can only assume is sloppy coding.
And of course you can make linux do almost anything you want it do.
