You seem to be saying (and be certain of) that in the EU, were Steam to be discontinued, it'd be completely legal for you to download a crack to bypass the DRM for the game you were previously licensed to play through Valve's platform. Is this established as a matter of law? Could you share any links on the topic?

If it wouldn't be legal, then downloading the crack to the game you paid to play through Steam but can't anymore would presumably be just as illegal as pirating the whole game to begin with. Did you really purchase the game or just an indefinite (but not necessarily eternal) license to play it?
