Proton users are reporting subscription cancellations after revelations that CEO Andy Yen pressured engineers to embrace AI and dismissed a request for more security testing as “loser thinking.” The Swiss privacy company has since canceled planned employee assessments of AI use.

Its encrypted email service scrambles messages to protect their contents, and customers questioning its development practices are asking whether faster releases could come at their expense.
