But I'd nonetheless argue that the primary issue is not that Adobe is implementing new licensing schemes of dubious value. It's that Adobe implemented them in an exceedingly invasive way. I don't use Adobe Digital Editions unless I absolutely have to, but until now that's been because the software is awful, not because it's philosophically objectionable.
I'd also argue that it may not be entirely fair to describe Adobe as "obsessed with rights management"; they're providing a platform for publishers, and using DRM -- or not -- is the publishers' choice. The chances are high that the "metered licensing" concept was borne of publisher request, not an Adobe plan to make everyone's life difficult. Making everyone's life difficult is just Adobe's standard execution plan.
Are they selling it to third parties? Unless this is the case, then I'd say their obsession with DRM and rights management is the primary issue. Without of course discrediting that digital surveillance is the new standard.
