There is much more to the 'Potsdam' story than presented by 'Walking away'. Society publishers, while they produce a small profit for societal activities, are not the problem.
Commercial publishers who raise prices year over year, while publishing fewer and fewer articles are the real problem.
One wonders how long the current speed of review/publication can continue? I found it disappointing that no distinction was made between commercial publishers (Wiley, Elsevier, etc.) and responsible society publishers (APS, ACS, RSC, etc.)
