Jon Treadway and Sarah Greaves, in their August [Scholarly Kitchen post]( predicting more consolidation in scholarly publishing, doubt that scholarly societies will leave their commercial partners:

> [I]nitiatives like Plan S are having the reverse effect, magnifying the importance of the scale and expertise offered by large commercial publishers. For smaller publishers, they provide reassurance, scale, and tools to comply with Plan S and other funding initiatives that they alone will find hard to implement after years of reducing internal editorial and publishing offices. 

It's a [depressing read](, partly owing to the authors' pose as industry analysts. The [piece](—definitely worth reading—comes off as market advice to would-be investors.
