It is a legal, free release from a developer. The original mirror is on their website and I fail to see why a release of a free product, well it's sort of a mod, though a torrent -so it has faster speeds- would be encouraging piracy. I think this actually highlights one of the major issues with torrent sites is that they, in fact, have legitimate uses as well as less-than-legal ones.
Posting a link to one of the biggest websites promoting piracy is suspect judgment to do on a software developer's website. He'd have been better served posting the torrent directly rather than linking to that site.
Legitimate uses indeed. Buying something from a known fence, even if that particular item happens to not be stolen, still supports that fence. But I guess people will make whatever rationalizations they need so they can sleep at night.
Sure the release is free and you can find a legitimate torrent for it. If that's the case, post a link to a torrent site that only posts torrents of freely available software.
Even if people clicking on that link only downloaded that torrent, they still generated ad revenue for a site who's primary purpose is to share torrents of pirated software.
Well, that's easy. Just upload it to a torrent-tracker that doesn't host copyrighted material.
