You can look through my history how many times I’ve brought this up to people and they just don’t seem to care. A defence is that they’ll buy the domain for a century and not care once they’re dead which is fair but the situation in this article is a valid one. I will always stick with Big Email for accounts.
I moved to a third-level .name domain in 2005 precisely because one of the Big Email providers (Google) locked me out of my account with no recourse; presumably because I had a very common email address that was getting a large number of login attempts from other people which had triggered some abuse automation.
At the time - before the explosion of new gLTDs - third-level .name domains were advertised as the 'correct' domain to register for individuals wanting personal email addresses.
