Surprised I don't see anyone else mentioning this. This looks to me like typical Microsoft strategy that they utilized a lot 25 years ago. 1. when not leader in given market, make your product fully compatible with competitor 2. start gaining momentum (e.g. why should I use Linux, when on Windows I can run both Linux and Windows applications) 3. once becoming leader break up compatibility 4. rinse and repeat Happened…
Could you name a single company that doesn't follow where the market is and try to monopolises it later? Plus, Windows is still the leader in the desktop and laptop market until today. They are facing some tough competition but "not leader in given market" is not true.
I think your argument actually supports parent's position, so this "plus" in the next sentence seems out of place :)
