I understand the sentiment. I certainly have my own bouts of intense paranoia related to security and the privacy of my personal stuff. It can become unhealthy. However, I think as long as the majority are complicit with email providers that don't offer end-to-end encryption, we may fall deeper into the clutches of government surveillance, targeted advertising, and other practices that IMO are an overall toxic influence on humanity. I don't practice what I preach at the moment but hopefully the loss of convenience is not too significant as I make the switch.
