You were being mislead with false information. Share appropriate sources to back up whatever you are saying. Proton has regular audits for security and encryption for all their products, which makes whatever you’ve been told pretty much false information
What’s more likely? a) I’m being mislead by someone that actually got into legal trouble that involved them and isn’t profiting in any way from it or b) You / everyone else that simply is eating their marketing and PR is being mislead in some way.
Truth is, none of us can prove their claims and auditors are true.
