This is a bizarre statement. MS could have developed Xamarin on their own, but they didn't. Today Xamarin exists and is a very powerful tool with a large userbase. If MS now decides they want to enter that space, especially since it is becoming more and more worthwhile due to mobile platforms, then it makes more sense to buy Xamarin than to work in parallel on their own. It also makes sense not to fragment the market for such products.
