Why there are so many successful AGN Feedback models?

The AGN Feedback paradigm has become a standard element of galaxies and galaxy cluster models. The uncertainties in the ICM physics and in the possible channels of a central AGN energy release currently preclude building a model from the first principles. This leads to a variety of suggestions that all claimed to be successful. We argue that this is a natural result, which is only weakly dependent on the model assumptions.
