I agree that it would be better if Google applied the same rules to other vendors selling similar knives. They are entirely free to decide how you can use their service, there's nothing evil about that.
Edit: To clarify, I've used knives professionally (diving instructor) and recreationally (kite surfer), but I fail to see the non-weapon use for a knife that is small (and therefore concealable) and also opens quickly. Not to mention the window-smashing attachment. [1]
