Your complaint is not new. Some people are not famous, but rather infamous for spending a career trying to claim they invented a new term, or were the first to introduce an idea, and so on. They’re the people you see citing themselves in academic papers, maintaining fake and misleading job titles, creating their own Wikipedia pages, and so on. Most people recognize the false modesty and find it all amusing, only the uninformed fall for it. Keep up the good work and celebrate your successes! Good arguments win in the end. Unfortunately, bad arguments often get louder and longer until they finally fade away.
