Personally i only purchase DRM free games, but it doesn't still change that fact that major digital storefronts use misleading terms. Maybe physical disks would maintain popularity if customers knew they'd be renting the product for unknown period time instead of owning it.
It's easy to forget that average joe doesn't understand the consequences when we're on our own bubbles.
Edit: The media outrage when Sony removed 550 movies, indicates the customers don't still understand the terms of the sale. It wouldnt make any noises if customers knew they were renting it.
As yes, the poor, ignorant average joe, who doesn't realize the game they buy on the PLAYSTATION store needs PLAYSTATION to work in order to play it. If only enough bloggers wrote enough articles to enlighten them, then they would join the mob and demand forever access to the games they play for 3 weeks then never play again.
