I see the "embrace" part. But I don't see any "extend" or "extinguish". Seems to be just FUD. Lots of cynical people wish Google was as "evil" as 90s MS, but that false equivalence just doesn't hold. It would only hold in some outlandish scenario where Google added proprietary extensions to RSS to make everything that operated with Reader incompatible with anything else, thus eliminating the main advantage of RSS as a common standard (like MS did with Java).
