I don’t usually delete stuff on purpose, but I am not as diligent as I “should” be about backing all my data. Sure, I back up the most important things, but the rest of it I won’t really miss if it gets deleted.
For example my Bookmarks/Saved Posts/Watch Later/Read It Later lists, they sometimes get deleted when I move devices and I don’t bother restoring them even when I can. Most of the things I add to those lists I know I am never going to read/watch. I add them anyway just to be safe, but I don’t feel bad if I don’t ever get to them. There’s only so much time in this world.
