From back when I set up my school game collection many of the big sites like crazy monkey games etc have a download page where you can get the .swfs, they want them spread all over. They have advertisements built into the .swf so the more accessible the game is the more people who see the ad and more money to the original site.
Yes, that's very good logic, you can tell your lawyer that.
