Mousecloner is very likely against the rules

[Tehtsuo]

He misrepresented his product TO Blizzard in an attempt to get a "sign off". Then after receiving a general "use at your own risk" answer back, he turned around and misrepresented the answer to his potential customers!

There is another word for this kind of behavior. Fraud.

You're drawing a conclusion based on your gut feeling about MouseCloner, not on actual facts. He did not necessarily deliberately misrepresent anything to Blizzard -- all we can really say with lots of caps and underlined words is that the confirmation from Blizzard was not based on a sufficient examination of the software. That's significant, but it's hardly a justification for using "fact" and "fraud" in the same breath.

Blizzards policies on third-party addons makes your gut feeling the single most important source of a judgment call.

In addition, the very reason Blizzard will not conclusively say "This application is guaranteed to be ok" is because they know people might try to misrepresent their products when seeking Blizzard's endorsement just like Evilseed has done. Hence their reticence when asked to give a definite yes or no answer, which unfortunately puts US in the position of deciding whether said application is worth the risk.
