I think their advertising copy about not logging IP addresses was poorly done, but their service is private enough for me. It probably doesn’t much matter or make much difference, but I feel OK with using their service, and tweaking my account settings for Google and Apple to the minimum amount of data retention.
I feel that people who let corporations easily have all of their data put themselves at a disadvantage when it comes to any interaction between yourself and any large company (insurance, retail, etc.). Governments will always have our private information so the real purpose of privacy is economic value.
Imagine playing poker with your friends and you had to have your cards face up on the table and they could keep their cards hidden from you. In this example, your friends are corporations.
EDIT: Carissa Véliz, author of Privacy is Power, was interviewed recently on the ProtonMail blog, and I think the interview does a good job of summarizing her excellent book: https://protonmail.com/blog/carissa-veliz-data-privacy/
