Easy to avoid on Macs. Harder on phones for non-technical types. The bigger issue with Apple is I think getting data out of iCloud should you want to do something else. Their proprietary formats and databases (especially for photos) is kind of a nightmare.
Apple heavily pushes their users towards iCloud subscriptions. More so on iOS than macOS but still.
