Not OP but many Linux project I follow, since they don't have many resources, publish their releases through Torrent, a seeebox is fairly cheap (something like €10 a month) and could be easily crowdfunded even for a small project, and isn't a huge expense anyway. And the site could just be a static page, or better yet the magnet link could be aviable on Github for people that want the precompliled binaries instead of the source.

E: did i say something controversial?
