Alison Mudditt, CEO of PLOS, in an interview with The Scholarly Kitchen about a year ago:

Back when PLOS launched and focused on the biomedical sciences, charging authors a fee to publish seemed fair and reasonable. Fast forward twenty years and it’s clear that we failed to anticipate how successful APCs would become and how some publishers would exploit this space. So, we’re on a journey at PLOS to move away from APCs entirely but it feels as if much of the industry is heading in the opposite direction with a headlong rush into “transformative” agreements. I can’t see any way in which this won’t continue to disenfranchise researchers in lower- and middle-income countries and so I hope that, as an industry, we can do better.

It’s good to see that PLOS is committed to repairing a system—author charges—that the nonprofit helped establish. PLOS was the second publisher, and the first nonprofit, to adopt the APC model at the turn of the millennium—and the organization chose a fatefully high charge ($1500) that would, in the next couple of years, pave the way for Springer-style $3000 usury.
