--- Comment #1 from Nikolay Sivov bunglehead@gmail.com --- Application developers are free to block their products on Wine, if they wish. I don't think we should any counter measures against that.
Sometimes it also happens that developers add wine detection to workaround some wine bugs, that might get fixed later. This is of course discourage, but it's different to what you've described.
