The truth is that OA is a childish illusion that got “absorbed” by the adults in the room who tapped the kids on their back and said “no worries, we’ll take it from here”. Then they turned traditional publishing, which was already an elaborate expensive ruse, into OA which is an even more expensive (but less elaborate) ruse. Now everyone is happy, except someone trying to do actual research and having to read 1000 meaningless papers a day.
