Description
It is widely believed that in the presence of positive cosmological constant, heavy black holes can exhibit behaviour different than the standard Hawking radiation, namely there is a possibility of anti-evaporation of such objects. We point out that all those results (obtained in different frameworks) rely heavily upon the identification of the Naiari spacetime with the Schwarzschild--de Sitter (Kottler) spacetime. We argue that it is incorrect assumption and, as a result, also heavy black holes radiate thermally. We also discuss possible meaning of this results for the primordial black holes' lifetime.
