I don’t think this is about removing copy protection to sell it.
It is more about that the crack they are now selling officially has been seen as illegal by the publisher/game developer itself. People have worked on this for no monetary compensation and therefore provided free labour to remove DRM. Now the publisher is banking on this free work, pretty much legitimising the crack. But none of the money actually goes to anyone who cracked the game, since that was still illegal.
If the publisher had just removed DRM themselves and sold those copies, no one would be outraged. But they exploit the work of people they keep condeming for cracking their games.
