> That's weird. Since it defeats the purpose of expanding their WiFi hotspots coverage. If people have capped plans, they are likely to disable that hotspot altogether and use their own routers to begin with, to avoid anyone switching it back on. If they wanted such thing to work, it had to be excluded from both monthly data caps and active bandwidth limit.

I think what he's trying to say is that as an individual using the xfinitywifi network the traffic counts towards your data cap. As the person hosting the access point, other people using it does not count towards your cap.
