Lol I don't think any clarification is needed.

If you make/use a program that sends input to the client, trying to argue "but it wasn't sending data to the client! it only sent it to the OS, which passed it along to the client!" is just not going to cut it. That's like saying you didn't send a mailbomb to your victim (you only sent it to the post office!).

The words I used were mine, not Virtus's. I could come up with more bulletproof language, but it seems unnecessary as the meaning is fairly clear. And, the use of general language in the TOS gives the devs some more flexibility in policing their game.
