A lot of 5G conspiracy theories might also correlate with incumbent ISPs (especially cable ones) who can block new wired ISPs but they can't block mobile phones - so a lot of the conspiracy theories included things like "wifi connected by cable to internet is fine" :V And 5G includes technologies that allow for much denser mesh, higher throughput, lower latency, and more clients per cell enjoying good service. So it could start supplanting wired broadband services.
