Unlikely. Google doesn't appear to operate that way, they are very careful with their hiring. And outside of hacker news and other tiny techie/startup circles this hiring (and the firing) isn't on the radar, I don't think it affects Microsoft's appearance outside of the startup community one bit.
Also, according to Don's blog the first offer from Google came 90 minutes after the news of his firing was out. Which seems more an indication that google really wants him, and less an indication of cold strategic PR calculation. Nearly everyone who's been following Don Dodge's work was surprised by MS's move and considered it a mistake, so google's move is not surprising in the least.
