This foreshadows how Apple's model will devolve. I have been a Mac fanboy for a long time, and have always said that Apple wouldn't turn into Microsoft if they became popular. The good news is that it appears they won't; we don't see Apple promoting their inferior products with the goal of locking people in to their platform. What we see instead is Apple ardently defending Intellectual Property rights, even when there does not appear to be infringement. Only the clear establishment will be allowed in their channel, and only their channel will be allowed on their hardware.

This is more avoidable than file formats: one can easily switch to another operating system without repercussion. Unfortunately, there aren't many good alternatives.
