Why are you concerned? The article says that they expect Google to announce services/software/specs that phone makers can use. That sounds like they're going to be doing things that help Nokia, not hurt it. A standard suite of software that could be run on top of, say, Maemo. Especially once the WiMAX version is out.

Now, if Google releases a hardware phone platform, instead of a software specification, then, yes, I'd be concerned about that.
