Amazon discovered they didn't have the rights to a book in Canada and deleted it off people devices. The book? 1984.
I think the iTunes issues have been fixed, but it's still stupid to not have your own backup independent of stuff accessible by "cloud" services.
I buy everything I can off bandcamp and download it to my machine. I occasionally buy off Amazon music, but I really hate it when that's the only option an artists has and would prefer to buy/rip a physical CD at a show. I keep my music on a 512GB microSD card (crazy these things exist now) and I always keep my own backups of my own content; buy DRM free whenever I can on Gog/Humble over Steam.
I prefer to have things I own, not licenses to software and content that can be revoked at any time.
