I'm not sure why. I think most threads of any type usually feel the same as other threads of the type. As for your Windows hypothetical, not sure which Windows you're talking about, but I don't think Microsoft would really care if you did the equivalent of the projects being discussed to Windowses of approximately that age. If you do something obviously different, like freely distribute a modified Windows ISO as your own, I would expect to encounter some resistance.
