I don't think that's really a good comparison of what happened with Kali, battle.net etc. (there was actually another one before Kali but I can't remember it's name).
It's more like a great indy iPhone app that increases the value of the phone and even becomes one of the reasons people are buying the phone. Then Apple decides to build the same functionality right into the phone making the app obsolete. That's a much better analogy.
Now I'm not against Apple doing that at all. In fact I think it's a no-brainer, and failing to do it would be disappointing. It's just a shame that the little indy guys who created that market for them get shut out. Toss them a couple million bucks or something you know?
