I mean, locking users into your platform is one of the most common ways companies make money and keep making money. And that works.

If you want an obvious example, look at Apple.

I guess my point here is that being closed is directly against the goals of the technology. Apple's lock-in is either a side effect or potentially even beneficial to their goal of providing a good phone/computer/whatever, whereas commercial lock-in is fairly clearly opposed to creating an API ecosystem that is usable across a range of technologies/consumers/etc.
