It's a license, same as any other. Either you accept it or you don't. But if you do, then you're expected to be true to your word. Welshing on a deal, that's far more "evil" (a word that has totally lost any meaning on the Internet).
Don't expect people to be bound by forced promises.
If I was in a different societal context where I could say 'No', and you know, shoot someone if they got pushy about it, then I'd be truer to my word. But given that I can't there's no choice but to lie - I'm certainly not going to stop learning just because someone told me to to preserve his market share.
Also, the same thing applies to DRM removal, etc. Once I buy a product it's mine - be thankful I didn't just warez it in the first place.
