Calling it a "free and open channel" when 80% of consumers are on Microsoft/Google addresses that control who can deliver e-mail is laughable. It's dead, Jim.

Fair point - I meant free in the sense that the protocol is open. I didn’t mean that it’s not under threat.

You seem to miss the point WHY customers go there. I, for one, switched when I realized Google filters spam effectively.

That WHY seems to only address a very small slice of the market. Some other WHYs I've encountered

- it was a way to outsource the mail server administration and already free in our corporate package

Which is pretty much all I have from the corporate side. On the personal or small business side its most often

- I don't really care that much about running my own stuff

- I needed a personal email address

All these are valid reasons/motivations but none explicitly argue that email messaging should become proprietary.
