He's not wrong though. Bruce's sidekicks are messed up and he is a bad role model. Damian was called out for having an illegal secret jail. Who has always had an illegal secret prison in the Bat cave? Batman. Who bragged about having a secret jail under the JL hQ? Batman.
Admittedly Damian and co are taking thing's a step further channelling the JL by messing with mind wipes [though unlike the JL they haven't stooped to wiping heroes minds for selfish reasons]
The TT need supervision and the older heroes need to remember they are role models
