And that is where I disagree. Something like UltraViolet for rentals, or all-you-can-eat plans, sounds perfectly fine.
But for purchased content? No. A thousand times: NO.
If I'm renting it, it's reasonable to have restrictions on it. If I'm buying it, I'll take just the bits, thank you.
No burden. No cruft. No phone-home or provider-based device support decisions. No fine print that the service may disappear one day, taking my library with it. No fine print that any terms may change post-sale. Because it's a sale. Not a license.
Just the bits, thanks; in a standard format.
