I am happy enough using ProtonMail and calendar, Duck Duck Go, and Apple services. But, I use tons of Google services that I pay for: Youtube Premium via Youtube Music, Google Photos (pay for extra storage), books, GCP. I like being able to search Google Photos, and that is one killer feature that Apple Photos does not have (my iPhone automatically uploads all pictures to both, as well as OneDrive). As individuals, we all need to decide where to draw the line re: privacy. I found a setup that I am comfortable with.
