If they would have made it as simple as that, it wouldn't be a problem but the point the movie made was that apex was to blame for Godzilla rampaging. So they painted Godzilla as a villain but then he wasn't actually villain. If Godzilla was just jacking stuff up to bring out Kong and show he is the bigger alpha (which isn't out of character for him) then its completely fine imo. But he was rampaging because he knew that an unpowered mecha godzilla was out there?
