Richard Poynder has published "On Sponsorship, Transparency, Scholarly Publishing, and Open Access" in Open & Shut?
Here's an excerpt:
Sponsorship and lobbying (which often amount to the same thing), for instance, have assisted legacy publishers to co-opt open access. This has seen the triumph of the pay-to-publish model, which has been introduced in a way that has enabled publishers to adapt OA to their needs, and to ringfence and port their excessive profits to the new OA environment. Those researchers who do not have the wherewithal to pay article-process charges (APCs), however, are finding themselves increasingly disenfranchised.
