The other name it went by is Project Astoria, you can find a lot of the Internet about it. There's pretty much no chance of it being released at this point, unfortunately.

Microsoft and Google each have subtle and not-subtle ways of attacking each other. Google doesn't really feel threatened by Bing, everyone thinks Bing is a joke (even if it is pretty decent), plus Google steals all their best ideas from Bing. But things like the popups Google has on their sites to tell Edge users Chrome is better, Microsoft's retaliatory popups in Windows that tell Chrome users to try Edge, etc. Google has aggressively broken compatibility of their various services with Windows Mobile devices before. They definitely have options if they want to harass the others' customers.
