While cable boxes could be replaced by subsidized smartphones, my question is "Why?". A wired connection will always be less capricious than a wireless one [citation needed], so if your TV is in a fixed position there's no benefit. At best, you could get a little bit of flexibility w/in your domicile, but wouldn't this problem be better solved with better wiring? And who moves their frequently TV anyways?

Also, before anybody comments something about 5G helping out in broadband deserts, I'd argue that point is invalidated by the reduced penetration depth due to the much higher frequency of 5G. Let's just invest in rural broadband instead

A smartphone can probably deliver better-personalized ads since it can be tracked to an individual person. No benefit to the consumer, really.

We as a society, might benefit more, but, like socialized healthcare, that's not how the market works. The bandwidth to support renting out smartphones-as-hotspots for home wifi connections will make Verizon wireless and AT&T quite happy (at Comcast's expense), so the question is less "why", and more "who, and for how much"?
