Knowing what we know now that blog post is kind of amusing. Apple's Lightning appears to be less sophisticated than the DHL video out over micro-USB connectors it complains about. It's like Apple said "screw trying to get a proper video out, we'll just cram it all down USB 2.0 and lossily compress the hell out of it to get it to fit, then stick an entire ARM SoC in the adapter to decompress it again" - it's the most kludgy solution imaginable. (I have no idea whether Lightning actually uses USB 2.0, but it seems to be in the same ballpark bandwidth-wise.)
