I think #3 is the sticking point. I can read it, but a lifetime of reading has trained me to use capitalization past a period and space as a prompt to some sort of change. The lack of it makes a paragraph read like an unbroken sentence to me. It slows me down considerably. I'm not defending or agreeing with the complaint, just trying to find the reasoning behind one of the positions. I think people should step back and see what's actually bothering them about the writing (or if there's anything fundamentally bothersome at all).
