@koen_hufkens Does that guarantee that authors specifically get paid, or only copyright holders?
The copyright licensing scheme in New Zealand pays the copyright holder - so if the publishing agreement the author signed transferred copyright to the publisher (common in academia for books, and near universal for journal articles without a Creative Commons licence) then the payment goes to the publisher.
@zeborah @RustyBertrand Haven't bothered with the details (but I should). From a colleague I know they got like a 200 EURO pay day (on their academic work), from where and how this is calculated remains opaque (what fraction was open access etc). The whole shindig is a scam anyway IMO, but at least you can be annoying.
