Even though I am on macOS, I have thought about leaving them, too. Mostly because I am paying a lot and their tertiary services such as calendar, drive and pass are lackluster. It feels like I am paying a steep price for them to focus on offering new products that are worse than the competition. With things like 1Password and iCloud drive (with advanced data protection enabled), it is hard to justify paying Proton hundreds of dollars for Mail and VPN alone.
I was wondering the same thing. Maybe in the USA it is easier due to our relaxed (almost non-existent) business oversight from the government? Not sure.
