Want facts?
FACT: Downloading licensed software without paying is illegal and called piracy
FACT: FS2 is licensed software, which downloading it makes it illegal, without regards if you downloaded it for linux or mac or DOS, or any OS you may want, it's still illegal.
FACT: Distribution of licensed software without the permission of the maker is still illegal, so what those circles are doing is illegal, and still, not hlp's business.
FACT: It was never "Free" to download Freespace2 as it has been told many times already.
FACT: GoG offers a way to buy this out-of-print game for a very reasonable price, and it's perfectly legal, unlike some sites that offer you a download for a fee without ever paying the makers of the game.
As i see it, you are proposing a change with the illegal means of obtaining freespace2 files to not restrict window users, but hlp has no control over this, you may want to propose this to whoever is offering those files, but i still think this is going no where ñ.ñ;;
