People complain because Proton specifically advertises privacy, mainstream providers don't. Which is pretty reasonable as far as complaining goes.

Good job on mocking others though :*

Proton does offer more privacy than mainstream providers, because they have less information to hand over when courts compel them.

Proton isn't perfect by any means, but the idea that there is no meaningful privacy difference between Proton and (for example) Gmail because both respond to court orders is flat-out false.
