There are companies out there that offer proxies from 'real' US resident IP addresses. I think these companies use tactics like this to be able to offer real residential IPs (and not IP ranges belonging to hosting companies)
This is the first one that came up on google - https://stormproxies.com/ - I'm not saying that specific company is in any way related to this device or tactic (it is just the first on google for 'residential address ip proxy', but I think it is companies similar to this that will pay people for access to their routers and sell that access.
