After analyzing more than 1k contracts, the verdict is in and it is clear:
"Our analysis demonstrates that research institutions seem to be 'trapped' in transformative agreements. Instead of being a bridge towards a fully #OpenAccess world, academia is stuck in the hybrid system. This endows the legacy (non-Open Access) publishing houses with substantial market power. It raises entry barriers, lowers competition, and increases costs for libraries and universities."
