The problem is not the utility these services provide -- which I agree scales with the amount of data you can give them! -- but rather the use of this private information in a number of ways (legal or not) that provide no benefit to the user, and in fact can be considered downright dangerous to the user. This, I believe, opens the door for a company like Apple or otherwise to create a machine learning company with security at the forefront -- in essence, what if these useful machine learning models you use everyday were able to be locked down, so the personal data used by the model was only viewable by you, and NOT an employee of the machine learning company who produces said model?
