Not sure this fits in the community but I felt it is an important topic that needs visibility. Researchgate made a deal with MDPI to prefer some of their journals on the site over other publications or journals. It will likely be impossible to know if suggestions you see in the future are genuine or paid for by this deal.

MDPI made a post on their site about this https://www.mdpi.com/about/announcements/7051

I could not find an announcement on the Researchgate site so far. Possible enshittification of Researchgate up ahead?
