Ah well it's a matter of point of view anyways. Nintendo would say Sony stole their idea, and of course no breaking of a legal contract was involved, but Sony definitely lost money when they got led on and dropped like a nerd by a pretty girl. Basically Nintendo was wise in backing out of a deal which would give sony the rights to the Super-CD format, which was to be Nintendo's system following the Super Nintendo, co-developed by Sony, particularly the drive.
But that's besides the point anyways. Corporations can screw each other over and fluffy pink bunnies will hop around in joy. It's great. But from my times of my Nintendo dork days I learned that they are a bunch of liars not excluding to their customers. They all are, so might as well go for the better game console if you're intrested in that. Of which the Nintendo consoles are not.
Oh and about this:
They all stink for depending on something that anyone can just copy for a friend (music, software etc), and then being such asses whenever people do copy for friends.
Sure, Nintendo actually made it hard to copy out of some random drive with their own crappy inferior disk format which gives the developers a hard time and less space, ultimately something less-than to the end consumer, just to save their own ass. Which is fine, but in being pragmatic, I'd go for the better format/system regardless, which has tended to be the Playstation ever since the first one.
