I'm not disputing that...but like I mentioned in the post; I'm ruthless not spending time on things that aren't our core service. I don't host our own mail either, I pay for GSuite :-P.
As a business, I completely agree - streamlining to focus on what matters. As a individual person, I am also the kind who hosts my own mail server - and, well, everything else <- Not a fan of the NSA.
