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?

If that pronunciation is based on a lie that solely exists to discredit God's revelation, then no, it's not a good thing.
It can't be an attempt to better understand Hebrew because it's not Hebrew. The Hebrew doesn't have vowels.
