Remove Sentry
All or most Proton apps bundle Sentry. This is allegedly for crash reporting only, but Sentry can do way more than that (e.g. profiling for performance, seeing how users navigate the UI and where they get stuck). I would like to see Sentry removed.
Proton's entire business is staked on privacy. However, telemetry software like Sentry is fundamentally incompatible with user privacy. As a user, it is not feasible to thoroughly vet what every tracker is actually collecting, especially because this can change at any time. The best way to reliably avoid unwanted data collection is to exclusively use apps that do not contain trackers.
All Proton apps should clear the bar of being telemetry free. To an app like Proton, privacy should be king and well worth minor theoretical tradeoffs to stability.
