In MOS it's not just about Superman, he's not only entity who can trash cities - it's Zod and the Black Zero - who nearly destroy humanity. Her dined't jsyt do "crazy things," he saved the world with the military in front of everyone. That's a game changer, B vs S explores this with the media, it's why he's seen as a god by people. But the woman who saved the world from World war 3 by communciting with everyone is not mentioned? That makes Superman far less of an unknown, he came years after she did that. Wonder Woman doesn't need an interview, she personally talked to everyone on Earth and saved the world by making people revoke wishes (congrats, magic's real in the 80's!) and stopping by then the biggest threat to humanity since Hitler himself. She stopped World War 3, and everyone would know her by that. They don't that she's Wonder Woman but they know a woman did that by supernatural means. The things which happened in '84 weren't small scale, everyone was directly impacted by that. More then they were with Superman in both his movies. Superman was been from a distance, she personally spoke to these people in their minds with singular speech. That changes human history.
