In your world consumers would be unable to tell the difference between the crappy clones and the original and probably give up on all of them.

Blizzard is, rightfully, concerned about consumers being confused and thinking that they are somehow involved in this endeavor.

Lastly, if their scrappy open source game is better than Blizzard's, they shouldn't need Blizzard's assets. Unless of course, it was the Starcraft identity that made it "good" in the first place.
