This is where the car analogy breaks down: we can reasonably expect that a BMW or Mercedes can use the same roads as a Dacia. But once Apple doesn't have a significant share of the smartphone market anymore, Google and others could easily lock them out further by making services that are Android-only. It's hard to ignore a 40% audience, it's attractive to bully a 10% audience, that is willing to pay huge margins, into switching to Android.
