Yes but as I said how will it **** IW off exactly when they will be none the wiser to it? They'll just see loads of people downloading the torrent - which would've happened anyway - and figure "oh well PC piracy is just as bad as we already figured it was". There's no logical connection between those numbers and who would otherwise have bought it, and as such there's no meaningful statistic to learn from it, therefore pirating it thinking "they'll think twice next time about omitting dedicated servers or leaning!" is dumb.
All you're doing is adding +1 peer to a torrent, they don't know whether you're downloading it simply because it has no dedicated servers or whether you had no intention of buying it anyway, and ultimately all it will do is make them (and other companies watching it) figure consoles are the way forward.
