I'm guessing you're referring to this: http://lwn.net/Articles/153990/ http://lwn.net/Articles/153990/ I remember that, long ago; I don't think there's anything wrong with not wanting users of your product to leverage it to build a replacement nor disallowing it in the license. I think where people (including myself) have a problem, is claiming that mercurial somehow has ripped off something from BK. From vague memory, BK laid claim to using a DAG for a DVCS? I assume you must also think that if someone is first to implement something that can be trivially found in an introductory computer science text, they have a patentable claim? Ironic that "largefiles" is a user contributed extension, and that only mercurial seems to be guilty of "copying," but git must be so different that it's unworthy of being sued?
