As a guess? The same amount of customers that left Gmail for Proton vs. those that signed up for Proton without ever having a Gmail account.

I’d wager that most of their current customers have left something else to sign up for Proton in the first place, because of the privacy and security offering.

When Proton leadership abandons those values in favor of “move fast, break things, lay off engineers”, their customers are more likely to follow the people that take privacy and security seriously.

The CEO and CTO have made it clear that they want vibe-coded product updates without pentesting before exposing their customers to whatever may happen.

If you bought into Proton for privacy and security, that’s a red flag and a sign to find an alternative.
