Is there some fields where this is way more of a problem (I'm guessing medicine)? As someone in computer vision you are often dealing with IEEE for conferences and journals, which has never struck me as that bad, although for a non-profit and as a member I would prefer they were a little more open. It is nice that CVPR has been open access for a couple of years.
