Maybe calling it "Forever Root" was a bit too brash and egged them on to prove the author of the process wrong in naming it "Forever"!!
Let's hope that's not the case and that it will keep rooted status. I suspect it will not be too long before it can be rooted again, though. It's a cat and mouse game between the DEV community and Moto/Verizon DEVs. I would imagine that our "good guys" have the upper hand!!
