I hadn't heard of that thank you for pointing it out. This does make things look more optimistic. I would still define it as vendor lock-in though. The iTunes binary might be available for Windows, but Apple still claims control over your experience and your data.
While they are in control of your data, you will be faced with a question every time you upgrade your hardware. Do you want to interact with your own documents and music using a clunky interface, or do you want to use an interface that makes you feel more in control and happier?
The above question is a little contrived, but I believe that it is fairly close to the truth, Apple has always been a company based on making you feel good.
The photos and music are still stored unencrypted on your hard drives, and the metadata is embedded in those files, so no, they aren't controlling your data, any more than Dropbox does.
