I don't care if it's free or paid. If it has privacy flaws, they should be fixed, or people should be informed of them. Evolution Mail isn't interested in doing either of those things. So I'll do it for them. If you think that informing people is, "drumming up a mob", then you are wrong.

If your response to the idea of sanitizing HTML is a clown emoji, I don't simply not care if you quit open source, I actively want you out of the entire industry.

Hope that helps.

This is hardly an unreasonable request. It's exactly the right move in this case. If you don't feel like fixing anything, declare the project unmaintained and close the issue tracker.
