But nobody said "building on a Microsoft platform is a bad idea". What is being said is that "building on anybody's platform involves risk, whether it's twitter, microsoft, facebook, google, IBM or $WHOEVER". The point of this post was to highlight an example of the discussion around this topic and to emphasize that it isn't a novel thing.
