EU regulators aren’t politicians, they’re bureaucrats. The anti-trust office in particular is special because it’s practically the oldest EU institution, getting their start in the ECSC as regulators of a trade cartel, brutally cracking down on internal collusion both because presence of such practices weakens the whole and to make sure that national cartels are broken up, the very founding idea of the ECSC was to intertwine coal and steel industries so that internal war would become impossible because no individual nation actually had control over that sector.
