> De-Appleing is very difficult if you have a family using iCloud Photos, music, drive etc.

Although this is just anecdata, I moved my senior parents from iCloud Photos to Immich recently and their response was something like:

"Wow, the new Photos program on the iPad looks nice!"

For them it works out fine, since their use-cases are checking out vacation photos by scrolling the timeline and also occasionally clicking on the "memories" from N years ago. Helps that the app icon is very similar, too.
