Agreed. I got my own domain and moved off gmail because of this, but I can’t afford the time to help support everybody else doing that. (I do encourage them to at least move to a paid provider, though.)
These cases are super rare though, Google users getting rekt are much more frequent, that's for sure!
Not that any of the alternatives to DNS have yet proven to be half as reliable, but it's still fascinating how DNS is both simultaneously our best and worst hope for identity "ownership" on the current internet.
