Customers are those spending money posting ads on search. Frankly even they get crap customer support, but at least they are customers.
I'm no googler but it's clear "user support" (and "customer support") are not priorities at google, and that means other people _are_ priorities. So it's not exactly a shock to discover employees optimize to make other employees happy (measured) versus keeping users happy (not measured.)
I factor that in when I decide if I want to be more than a user, if I want to be a customer. (So far the answer is basically "no".) And, as a user, I understand I'm not a customer and Google doesn't care about me, or my gmail account... So I treat my gmail account with the importance it deserves.
So what though? This makes them happy, and they're all paid, so what does it matter what the outside world think or care?
