I missed this Ubiquity Press post from last April:

Until 2021, Ubiquity Press published all of our books under the Creative Commons Attribution license (CC BY) […] However, at the end of 2020, we were made aware that another company had taken a very large number of open access book titles that had been published under the CC BY license, including those from Ubiquity Press, and was re-selling them under their own name.

I’ve always been mystified by the fetishism for CC BY, particularly weighed against the CC BY-NC alternative. Cynical commercial uptake of the kind that victimized Ubiquity is the predictable result. Reacting to the same news, Martin Eve wrote:

I have to admit, today, that I was wrong about the risk of others reprinting open-access monographs produced under a Creative Commons license. […] Perhaps the -NC license should be considered, after all. Again, I admit that I may have been overly naive/trusting/hopeful in previously spurning such a license. The world is such a disappointment.
