Samuel Moore, in a post on the researcher data clauses increasingly tied into transformative agreements:
The datafication embedded within transformative agreements is worrying not just because of the increased surveillance it will entail, it also illustrates more general misdirection of the transition to open access and the potential danger of universities to use researcher data as part of negotiations. Open access was initially premised on the idea that publishers are extracting from the free labour of academics and privatising the gains through closed-access publications. But through transformative agreements, publishers are still parasitic on this labour in addition to their new strategies of extractivism.
