The point is, the copyright police have taken a fear (of something which has never occurred in actual law), and made it a point of battle.
This is, I think, the wrong forum for our disagreement. I mostly rose to your nasty casting of "copyright police", which was a mistake. Sorry to everyone else :)
But my final comment is thus; you have misconstrued, I think, the point of the argument against such links. In fact; pretty much all cases I have ever seen have been unambiguous in one way or another. So while I would entertain the notion that such a policy is limiting our ability to link to legitimately licensed/hosted content I suggest you kinda need to demonstrate that with specifics.
Perhaps an on-wiki discussion is the way to progress this.
