Important to understand why Science might take this route, why Nature hasn’t, and why it’s not a model other non-profit journals would necessarily risk 1/n https://twitter.com/cshperspectives/status/1350092111492874242

Science’s bet's that their subscription revenue is unaffected by availability of some fraction of research papers as free author manuscripts. The hope is libraries continue to subscribe because of the news and tertiary content 2/n

Nature has a ton of other journals to worry about, most of which don't have sufficient non-research content to sustain subscriptions alone. They need a business model that’ll work for all, so (author pays) Gold OA suits them more than green, given huge n of papers 3/n

For other non-profits, the Science route is risky as they typically don't have non-research content to sustain subscription. The Nature route is also tricky as they don't have high volumes of papers, economies of scale 4/n
