I suspect sometimes that the average consumer of PDF gaming material is more technically savvy than the average producer of same. Confirming my suspicion is Ginger Stampley’s post against Digital Rights Management in PDFs. It’s not the most scathing, detailed, fiery condemnation of DRM available online or anything, but PDF publishers should notice: your consumers have strong tastes, so strong that they border on moral codes, and they will not put up with your product if it bosses them around. I think that attitude goes with being comfortable on a computer and knowing what you can do. As for less savvy users, well, they aren’t the ones who go online and post all about how great – or frustrating, or sucky – your product is.
So be careful out there.
