Den Lennie posted a video to Vimeo that compared the Rotolight Anova to a competing product, the Kino Flo Celeb, and found the Rotolight product inferior. Rotolight responded by filing a perjurious, fraudulent DMCA takedown notice with Vimeo (who, to its shame, honored it), claiming that the review violated Rotolight's trademark. This is pure copyfraud: first, because the DMCA is only available as a remedy for copyright infringement (not trademark infringement) and second, because product reviews are not trademark infringements, full stop.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
