GPL doesn’t help you with them taking your idea and doing a clean room implementation.

You’d need to patent your idea to stop that.

Citing myself from my comment:

> As a result, this would probably forced Microsoft to develop a new one from scratch, because they're allergic to GPL, because if they have breached GPL, they would be forced to comply, since GPL is court tested already.

So, we seem to agree here.
