Similarly with Protonmail and GMail. How about email spam to start with? Or maybe email search? What about automatic filters? Or what about the fact the Protonmail is a subscription service if you want to use their advanced features.
I don't use any automatic filters, but I could use their "Bridge" tools and install Bat on my Laptop and setup filters this way. Way more advance features in Bat than in Gmail.
Protonmail is subscription service, true. But just like I can afford $5 per day for a good coffee, I can afford $1 per day for a secure, encrypted email; although I can believe for someone living in third world country, $30 seem a fortune, and I don't blame you for your country's economical situation.
And if you prefer gmail for free and be their product that they analyze, dissect it and categorize you based on the content of your email then that's fine with me; I really don't care. You are simply their product, but with your HN username, I doubt I had to tell you that :)
You seriously had the audacity here to compare GMail (a wonderful free product) with Protonmail (a $365/yr product) and ask me why I don't find it as a good replacement. At the very least, have some empathy man.
And if you don't believe me, Edward Snowden would like to have a word with you.
