I don’t think you can really stop these types of topics from getting popular, because it’s the crowd that the Fediverse attracts unfortunately. I tried to refer friends but the Fediverse system is too unnecessary for their needs and I respect that. Unless there’s some way to simplify the entire concept, or ways for newcomers to be easily onboarded, I fear all of this is going to fall into the same niche hole as the Linux community.
Not everybody uses social media the same way and some people need instant exposure to the community to get a better start. It doesn’t help that these types of posts just make people feel like they’re stupid.
