I didn't know there was a contact tracing functionality on Apple devices. I didn't know also about the Firefox extension to containerize accounts, will try it! For me just the fact I couldn't copy files from a phone to a computer has been a deal breaker. Also 10 years ago I had really a hard time to understand how the "cloud" could be better than my external hard disk to save data. So for me the transition to the cloud (even nextcloud) has been almost non-existant. When reading your article I feel happy I didn't fall into the Apple digital prison.
