Exactly, there were two different groups of users involved there...

Many of the people who first downloaded the pack were simply using well established and normal methods to access a repository. There wasn't anything to alert them that they were acting against the wishes of the system operator until they dug a little deeper. At which point the thread started and people realised what happened. I'm sure that the Rovio guys bear this group no ill-will

The second group of users were those who had read the threads discussing the problem and choosing deliberately to avoid paying. These guys were acting immorally.

The actions of this Sio guy fall squarely into the same class as the second group above.
