My biggest complaint about Monoprice is they've jacked up their prices over the past several years to switch over to the "free" shipping paradigm. Cables used to be less than a third of the current prices. Now they've tacked that one-unit shipping cost onto each unit even when you're buying more than one. I get that the market is heavily attracted towards lazily clicking "buy it now" on one or two things, but I really wish vendors would figure out a way of reconciling "free" shipping with the efficiency of batch ordering through significant quantity/order size discounts and whatnot. Maybe Monoprice will eventually get there with their business account type, but I haven't seen signs of that yet.
As for the original article, cool protocol dissection. But I can't fathom needing to care about HDCP versions. If your video source makes you deal with hostile anti-features, get a new video source.
