It starts at the first word. It's not buying anymore, for most things. It is getting a permission for a restricted use of it, not even renting. And still, they charge you as you were buying. The original company is still the owner, and can do and undo whatever it wants. Imagine "buying" a house, but the real owner can kick you out, put someone living with you in some of your rooms, install their security cameras, forbid you to put some furniture or have a saying on who can invite you there. Also, piracy is as stealing as taking a photo of your car is stealing it. You still have your car, someone that wouldn't buy it anyway won't pay for that neither. And probably the person pirating it will have more rights over the thing they didn't pay than a lawful buyer would have over the item he fully paid and "bought".
