On Twitter we frequently see frustrated posts by open science researchers complaining about another paywalled article by open science people on the topic of open science and open access. Most recently, Felix Schönbrodt, psychologist, metascientist, open scientist, and founder of LMU Open Science Center, published an article in Nature: Training students for an open science future. The article is behind a paywall.
One of the comments in the latter Twitter post implies that this criticism against Felix is the reason why he’s currently taking a break from Twitter. I don’t know whether that’s true or not, but I would really like to hear people’s thoughts on this: Is it ever morally OK for papers on open science to be published behind a paywall? Is it morally OK for open science enthusiastic researchers to publish papers on other topics behind paywalls?
