Apple software quality is in serious danger precisely because of this type of community and infrastructure rot. They are not encouraging developers to help them, and a not-surprising number of serious issues have shown up in released products in recent years.
I am one of those people who gave up on BugReporter. Lots has been written on how tedious it can be but even its “rewritten” version a few years ago is frustrating (basically you could be reporting a damned spelling error and they would still want a “sysdiagnose”). Bugs stay open for years and still can somehow be Duplicate. Meanwhile, very obvious broken features make it into new versions.
