I don't think the marketplace does a good job of explaining the difference to people. That might change things. Maybe. Probably not. >sigh<

On the other hand, the confusingly named DIVX (not the codec) expiring DVD-esque format (so you could play the DVD for 48 hours after purchase, and then after that you had to pay to watch it again. The format totally failed in the market and brought down Circuit City.

So that suggests it's a user education issue.
