I just came across these "disturbing facts about proton mail". Let's say, hypothetically, that I administer a small org that now wants to move away from proton.
I guess I should just learn pgp, but that would be a tough sell for any boomer members.
EDIT: thanks for all the responses! It seems like my intuition was correct: email is inherently insecure, and proton is no worse than other email providers insofaras you don't let their marketing cause you to drop your guard. If it's illegal, keep it offline.
I eventually left a lefty regional Discord server because none of the zoomers on it could even conceive of digital security. Unless the people in your group are explicitly technical I think you have a steep hill to climb for any practical solution.
