I'm not tone policing but contesting the premise that "aggressive tone" = "direct". For example
>(Windows took a different approach and got it right. In Windows, it's okay for multiple DLLs to provide the same symbol, and there's no sad and desperate effort to pretend that a single namespace is still cool.)
>(Windows got this right, where multiple DLLs can provide the same symbol)
There you go. Shorter, and not wasting 3 lines to express your feelings, and _you can still say Windows got it right_.
My feeling is that you can go in and describe a thing succinctly and to the point, and actually get your opinion across! It will be more effective, shorter, and your opinions are backed up with fact! No fluff needed.
