What's interesting about Xamarin is that they are very local about OSS (Miguel) but what they did was not very "open sourcey" - obtaining a perpetual license for Mono and this way making sure that no one else can put Mono on Android / iOS. Ever.

And then charging 1000$ annually per developer, per platform.

On the other hand they've made something that developers love (from what I've heard, I've never used Xamarin's stuff personally) so they deserve the credits.

Congrats to the team.
