My concern is if/when they come to dominate content distribution and become the only channel (or a member of an oligopoly of channels, all using "fair use" adverse licenses and DRM). At which point I'm effectively forced to lease rather than own my content, under whatever terms they dictate.

Apple still makes most of the money on hardware. They could not care less how do you get your content if you consume that content on the device they sold to you.

Frankly, I cannot imagine they going back to DRM for music on iTunes, and I hope it is only the question of time when DRM will be dropped for video and other media. If ITMS (where M will stand for "Media" instead of "Music") is the most convenient way to get your media and the price is right they will do well without DRM.
