The interactions are complex, as there are two scenarios:

(1) A network exists, but a fraction of the population cannot afford it.

(2) No (high-speed) network exists, and traditional commercial providers
are not building it.

(1) is more common in urban scenarios, but may also apply to the rural case
if you assume that satellite coverage is near-universal, but very expensive.

(2) is the low-density (rural) case.

This gets more complicated since you may well have an existing commercial
network, but at high cost or low performance. Thus, you have three options:

(1) Subsidize low-income consumers to use an existing (commercial) network.
See the new Lifeline service in the US that will provide a $9.25/month
subsidy for wired or wireless broadband. This is likely more effective in
cases where a high-performance network already exists, compared to building
a separate network.

https://www.fcc.gov/consumers/guides/lifeline-support-affordable-communications

(2) Subsidize an existing provider to extend their network into no-coverage
areas, with the assumption that this is more cost-effective than building a
new low-density-only network. (This assumption isn't always true.)

(3) Create a new provider for low-coverage areas.

In general, there are two separable issues:

(1) Who builds/owns/operates (using what technology)?
(2) Who subsidizes whom? (Volunteer labor is a form of subsidy unless every
network user contributes equal volunteer labor.)

I think the draft could do a better job of separating the two issues.
