IMO that's not a hidden cost. That's a decision you made. The actual hidden cost is the electricity and time you spend by configuring and mantaining your services.
I think any Android version is better in terms of privacy than iphone. iOS is property and a lot closer and less customizable than android.
If you are really concerned about privacy, my suggestion is not to use iphone.
