I'm surprised their profit margins are only 40%. Where does the money go? Based on my experiences, copyediting is generally done by a mix of broken computer algorithms and offshore indentured servants working for pennies/hour. Has anyone actually read a physical copy of a journal in the last 10 years that would necessitate mass printing press equipment? What else do they do that has actual cost? Do executive salaries/bonuses count as operating expenses? Maybe that's it.
My retirement dream is to disrupt/displace the entire academic publishing industry with an internet forum. Reviewers respond publicly, original post gets edited accordingly. All changes tracked/archived ala REDcap. Forums are divvied up by field and science quality. If you post in JAMA tier and people respond with why your study is a dumpster fire a moderator moves your study to unite with its fellow garbage science. The review process is perpetual, not limited to a few people and if new issues become apparent a year later from people commenting on your post who were not the initial reviewers, you get moved as well. Data and code is mandatory to build into the post. Some built-in tools to facilitate formatting for easier reading than traditional forums. Your account saves your personal annotation of all documents in perpetuity in the cloud and accessible across devices.
The technology to do this has been here for 10-20 years. Storage for the data files is an issue for certain fields (i.e. imaging, genetics, many basic science fields) but that's changing fast. Would need to crunch the numbers but factoring out storage of actual raw data I'm reasonably confident I could run an operation supporting the entire scientific enterprise for less than what elsevier pays their CEO. Would still need volunteer moderators and reviewers, but that feels less icky with no publication costs and nothing paywalled. Could support the whole thing off some unobtrusive banner ads for academic jobs and research gadgets at 50 bucks a day.
