It’s the genealogy of the idea.
It was explicitly created by a crackpot to libel Christianity and undermine the historical consensus, and only became popular again when the churches began adopting radical social liberalism.
Why would we ever allow such a thing to be accepted?
To be honest I think you are reading to much into it. In my experience, people who use that word are folks trying to learn a little bit about Hebrew to understand better things from Jesus's point of view. Any attempt to pronounce it closer to the way it was first pronounced seems like they are making an attempt to understand better who G-d is. And isn't that a good thing over all?
