it reads more like marketing material.
So do 95% of fan websites/blogs/tumblrs/twitter feeds, but that doesn't make them PR plants. Also, I don't think a plant would use the phrase "HUGE mistake via BBC America," even as part of the cover story.
People who imagine this is a PR stunt of some kind don't seem to get the scale on which actual PR works or the audience at which it's directed. If someone pitched "We'll leak the Blu-rays early to this one Tumblr nobody's ever heard of!" or "We'll invent a Tumblr and claim it got the Blu-rays early!" as a marketing tactic, the next pitch he made would be to McDonald's, about how good he is at saying "Would you like fries with that?"
