The argument is based on theory of historical fraud that is somehow become a mainstream and goes unnoticed. g-factor has been measured again and again. The problems with renormalization have been known. Initial theories have been refined and reformulated to be better, criticizing outdated formulations does not change physics.

It's a conspiracy theory with sparkle of equations.

Mainstream censors non-mainstream, hence for half a century we are staying in place e.g. quantum gravity, there are appearing new problems ...

The paper claims there are problems already with g-factor, could anybody explain why its objections are not valid?
