Every organization retires products, for which many people wrote a lot of code; I'm not sure what the objection is here, other than to that reality. Google does, Microsoft does, Twitter does, etc. Open source organizations do it too. Only enterprise vendors will support unsuccessful products for a long time, such as IBM's long support of OS/2. Mozilla also has products they've supported for a long time, including Firefox and Bugzilla. > I saw XUL I know they're phasing it out in some ways but hasn't it lasted around 15 years, since before Firefox? Some people think Mozilla stuck with it for too long. It's possible XUL is older than a few (precocious) Mozilla contributors.
