I felt this "prison" very strongly with iCloud. Don't get me wrong, I think iCloud functions exceptionally well. It's an extremely well integrated cloud and works seamlessly with all Apple products. It's just that after a while I start to realize just how much of my life was sitting on Apple servers and what a dependency I had on Apple, hoping they are the good guy (narrator: they were not, in fact, the good guy) or at least, not as bad as the next best option (I feel Google has legitimately become evil at this point). I was constantly reading about security and getting myself worried, etc.
Finally I just bought a NAS. Synology is my current choice, but use whatever you prefer. A NAS can replicate anything the "cloud" can do, it's faster, it's safer, it doesn't rely on the good graces of any cloud provider. YOU hold the access to your data. As it should be. I still use the "cloud" for my backups with HyperBackup sending encrypted backups to Wasabi, but that is a different matter. Even if Wasabi decided to be evil, my data is encrypted before it ever leaves the NAS and Wasabi could never see my raw data like Apple/Google can.
The only thing holding people back from this, I guess, is price. Apple charges $0.99/month for 500gigs, while just the NAS itself with no drives will cost you several hundred. But man, not being worried about the latest cloud drama, government overreach, privacy scandals, etc is worth every cent. A Synology NAS with Tailscale is just about the safest place to put my data. All the Snyology mobile apps even pass the gf test for features and ease of use. I recommend a small 2-bay NAS to everyone I can.
