I agree with you, but I think this is more an issue with the way crypto and its advocates have firehose-marketed that corner of technology, than an issue with laymen who aren't interested. Crypto, web 3.0, etc. have been hyped as the future of the internet, coopting general concepts like decentralization as belonging to scheme-y crypto stuff rather than just a principle that crypto (ostensibly) aligns with.

I never got into any of that myself and am hyper-skeptical of it, but (hopefully) I know enough to determine that the Fediverse is not on the same plane as all that. I also wouldn't blame anyone who can't tell the difference.
