You're smarter than that, Tom. Stop using the terminology invented by a bunch of scammers doing their damndest to monetize (interesting word...) a rip-off. You've heard of fair use. You're applying the idea above and beyond the call of duty for your own work. There's nothing you're doing that isn't more than covered by fair use. (Just one example: The whole idea that you're supposed to pay again for what you already bought is nothing but more scammers' nonsense.) So why are you playing on their (verbal) field? Excellent article on this recently in Ars Technica by Tim Lee.
