Adsense users often complain about this. They don't seem to realise that they're not the customer. They're not even the product being sold.

I wonder what you would say when you personally experience a $15,000/mo sudden AdSense account shutdown in a bootstrapped startup, with confiscation of $30,0000 earnings already on the account. The email will be just a template to accuse you of "fraudulent activity", and there will be no human at all that you can call. Speaking with the first hand knowledge of the matter.
But customers don't have to buy from you, and they don't have to give you a reason when they stop buying from you.
