Should readers get permission to make podfic?

[jesse_the_k]

While I just argued that the act of podficcing adds "fannish value" to a work, I'm unsure that readers must obtain an OK from the writer to make a recording.

Since I'm a newbie, I did some research. While I don't think it's possible for a podfic to fundamentally change a source in the same way, I started with remixes, since there's the same "permission" issue there. It seems most remix challenges are based on a mutual remix: by participating in writing, each fan also permits their work to be remixed (with one "safe" work held inviolate).

The Fanlore Wiki told me:

Though remixing in both fanfiction and vidding has become enormously popular, not all fans embrace the concept. [... snip ...] Though some fans feel any story is fair game for remixing, others believe that permission should be gained from the author first before using their work as a jumping-off point. Many fans feel it's hypocritical to reuse the original creations of the copyright holders in the canon while protesting that anyone should be allowed to remake their fanworks.

Current metadata don't state whether the podfic's reader has the writer's permission. Would the absence, permission or refusal of writer's OK change how you'd choose or read podfics?
