To call it “shenanigans” IMO doesn’t give it due credit.
As for the PGP thing, I’ve been with ProtonMail since they were in beta way back in 2013-ish and one of their founding goals was to provide encryption that was accessible to even casual users.
And like it or not, PGP is a thing that is quite confusing to most people, assuming they even know what it is.
Besides that, they also don’t support CalDAV and CardDAV (syncing of contacts and calendar), which is something that groupware absolutely needs to be viable for me.
Couldn’t agree more. They really need to extend Bridge to support calendar sync.
