Earlier quoted context omitted.
Shit happens with every provider, free or paid; hoping it won't because you pay $400/month for it is foolish. The smart thing is to make sure it doesn't affect you much, by decoupling from the service and turning it into a replaceable commodity as much as possible. That means using your own domain, keeping backups, etc. Then, when shit happens, you can just sign up for another provider and keep going.
Shit happens, but with nearly every other provider, you can at least talk to someone to find out what happened and get your service restored, or at least get your data.
So, you're paying and giving up on a nice webmail client with two-factor auth (how many providers offer this?) for "finding out what happen". I don't think it's a great deal.
I'm not a Gmail apologist, by the way - I think there are valid reasons not to use it, like not giving Google a copy of your whole life - but I don't find their policy for when "shit happens" a real problem.
