The phrase "MAGA" became a marker of Trump affiliation. That in turn made it odious to people on the other side of the polarized political spectrum (few Americans have a problem with the literal idea of improving the USA, of course, but in human language signifiers can become associated with signifieds beyond their supposed literal meaning). Then, when some people sympathetic to Trump internationally saw that MAGA hats were 1) a marker of the "Trump tribe", and 2) annoying to their perceived ideological opponents, they too took them up. Thus things like QAnon and MAGA spread memetically to some of the protests seen in the last few years in Europe.
