Band 41 through a Magic Box is faster for a lot of customers. They may not have an ISP or a good ISP. By my definition, bad ISPs don't offer true speeds greater than 200Mbps down, are unreliable, ban or slow down certain sites and ports without telling customers, have no option to get rid of a data cap. AT&T for example offers 1Gbps in new condos and upscale homes, but leaves out neighborhoods with buried cable and even most neighborhoods with above ground cable (they had plans which they dropped). So many people's choice on internet is dial-up at 53kbps, ISDN dialup at 128kbps, ADSL at 3Mbps, VDSL with at most 75Mbps, rarely WISP, satellite has caps and can't do Zoom etc because of lag. (Most of these should be good markets for SpaceX etc.)
Then you also have budget reasons. 30% of American homes skipped their house payment this month. Why pay for internet twice? Many homes only internet devices are smartphones and tablets with LTE.
