Fennec dev here. Figured I'd address some of these comments.

UA overrides are not the only tool in our toolbox. They're deployed in concert with outreach from webcompat.

UA overrides are a way of breaking a cycle, not preserving it.

They make it feasible for Japanese users to use Firefox without manually messing around with UA overrides (e.g., using Phony). And that gives us leverage. And with leverage our excellent webcompat team can get sites to make changes.
