Why I switched from Gmail to Proton Mail to iCloud Mail?

I value privacy and was delighted to discover Proton Mail. Their solution sounded like a wonderful counterpoint to the dominance of Gmail and other ad-driven services. Once I read books about surveillance capitalism, I knew that I wanted to protect my data and experience what it means to use the end-to-end encrypted, open-source email provider called Proton. Although, after over a year of using it, I’m switching to Apple’s iCloud Mail.
