This puts MS's decision to abandon Edge in a whole different light, especially if, as I understood it from this article, Google's push is about getting this into the Chromium, the open source precursor to Chrome, rather than limiting this cynical ploy to their Chrome implementation.
True, Edge and IE won't be mourned much, but monocultures, especially the likes emanating from Google (or FB) are not especially beneficial to individuals, companies or developers.
