Swiftfox - the perverting of an open source browser
Swiftfox is a Firefox-based browser, but there is one big difference between it and Firefox -- you can't share Swiftfox with a friend or place it in a repository of a Linux distribution because the Swiftfox license prohibits repackaging and redistribution.
Swiftfox developer Jason Halme writes on his site, "the licensing restrictions were put in place to safeguard Swiftfox users against the possibility of obtaining tainted versions from anyone who may wish to maliciously alter the binary and redistribute it." But this in itself is a security concern. Normally lots of eyes would be on the code -- the files would be inspected as the application was placed in a distribution's repositories. Now, instead, new users are asked to trust the lone developer.
