@Alex the second, interesting you mention Xamarin: Microsoft also acquired Xamarin’s competitor – the java based RoboVM. Guess what they did to that.

Check out the ‘Lerna’ code stealing debacle. Yes one dev does not a company make but when notified they opted to cover it up.
What happens when they have all their competitor’s source code?
