You have to ask what Microsoft's original intent was in lobbying for this legislation in the first place. I can guarantee that Microsoft isn't going to pursue this sort of legal action against companies that are building products on Windows & Windows Phone 7. It is yet another attempt on their part to impose a tax on companies that aren't building on their platforms & the prime target is clearly companies building on open source platforms specifically Linux & Android.
