>Are all riders this god damn picky? It wouldn't surprise me. I imagine there is a great amount of antagonism between performers/speakers/etc and the venues.
For certain performers, it's pretty much necessary. Someone else has mentioned Van Halen's "No brown M&M's" clause here, which they used as a quick way to see if every line in the rider has been followed. That's especially important when pyrotechnics or special stage instructions are in the rider, because if the venue is following small details like "no brown M&M's", they're much more likely to follow large safety requirements.
