There is no "uncertainty" in this story, it's made up to outrage bait people who are "against AI". Telling people to disable random stuff in about:config (that does not even help) is not something a journalist should do. There is nothing to dispute here.

As it stands this article is just embarassing, dishonest and pure clickbait. If you can't be bothered to research (you even LINKED the Bugzilla bug AND quoted a Firefox spokesperson) then stop being a journalist and stop making the world a worse place.
