>Why would you expect an email provider to also provide a calendar?

Because calendar has become a key part of a productivity suite and Email is the keystone. We use Protonmail right now to avoid Google or Fastmail or someone serving up all our emails in a warrant. We keep sensitive stuff off Protonmail of course but every bit helps LE build their case against us.

Protonmail should have calendaring, wiki, and on and on. An encrypted replacement for Exchange eventually. We disable all audiovideo hardware for core members but I can see even secure voice being useful for our contractors to use.
