Maybe open up a bug report? http://code.google.com/p/ie6-upgrade-warning/issues/entry http://code.google.com/p/ie6-upgrade-warning/issues/entry From the looks of it, the author is a junior coder or new to this sort of JS library code. He may not know any better, but keep in mind he's just looking to help by releasing this-- we were all newbie devs at one point. Overall, I'm not a fan of disparaging any code people release for free. There are too many developers who keep useful code locked away on their disks because they're afraid people will mock their work. Don't get me wrong, it's very helpful for potential consumers to know about the issues you mention, but there may be a better way to phrase your criticism.
