The purpose of this comment is to show that a reinterpretation of the resultsfrom the Letter: "Physics and Metaphysics of Wigner's Friends: Even performedpre-measurements have no results" allows for reaching the conclusion"pre-measurements have no resul" [arXiv:2003.07464] based only on postulates ofquantum mechanics without additional assumptions on irreversibility.Additionally, with supplementary reasoning based on Bell's theorem, one canshow that unitary decoherence cannot be solely responsible for thequantum-to-classical transition, and an additional irreversibility model isrequired for its full description. Consequently, the black hole informationparadox has no physical basis.

No-go for fully unitary quantum mechanics from Bell's Theorem; comment  on "Physics and Metaphysics of Wigner's Friends: Even performed  pre-measurements have no results''
