It's annoying, but calling it "outrageous" is just silly. How much do you pay them and what did they promise you for your money?
I have got used to this great free stuff too, but I don't believe I deserve unlimited free stuff, and I won't get all huffy when they take it away.
And they don't exactly refrain from mining my personal data once I pay for their service with cash. So, it is little short of outrageous.
Anyway, my major concern is that somehow my data stored with 'enterprise-grade' paid service still gets mined and resold to 3rd-parties. I'm being forced to pay while still it's me that's being the product. Privacy is a hefty enough price to pay for a personal email.
FYI that's not how google makes money.
