One good thing about PWAs is that they run inside a browser. So if that's a good browser like firefox, you can use addons to limit tracking. Or force dark mode even for apps that don't bother implementing it (eg the Amazon shopping app) with dark reader.
This is exactly what I dislike about PWAs: the move to sandboxing everything in the browser is a big step back because the browser silos everything in a non-composable way.
