If you are droning on about Photoshop then you are a poser that has no clue what Photoshop is used for. It's a canned Lemming Troll for idiots with no real clue.
I do my professional work with Photoshop. I wouldn't say I'm an artist (artists don't paint with computers), but I have very professional use for it. Yet you say I have no clue what it is used for. Care to tell me what it's good for, then?
If we go that route, then I could take Ubuntu and wrap it up in proprietary code. After that I donate to some Linux programmers who worked on some small part of it ("but Canonical just steals from the poor coders!") and it's justified!
Of course we can forget about the other people who worked on Ubuntu, just like we can forget about the other people who made that artists album happen.
