The even broader trend seems to be that the market leader does this. Microsoft did it with IE, Office, etc. Google is doing it with Chrome, Android, etc. It's possible there'll be something else "more open than Android/Chrome" in ~5 years, and then ~5 years after that it will be getting locked down in the same way that Chrome & Android are now. It might be a cyclic phenomena in the tech industry. Potentially startups can even exploit it by looking at what is in the process of being locked down and producing a more open competitor to it.
