Are community-run broadband providers cheaper because they are subsidized by taxes?

No, they are cheaper because the local monopolists/duopolists can charge the customers through the nose, as they don't have any alternative. Any form of competition leads to a reduction in costs for the consumer.

In addition, stuff like eight-digit compensations (Comcast: 37.5M $ for the CEO alone, https://www1.salary.com/Stephen-B-Burke-Salary-Bonus-Stock-O...), marketing (TV ads, but also sponsoring, e.g. Comcast/ESL) or the costs associated with running e.g. decades-old mainframe stuff for CRM/financial systems or simply maintaining even older copper lines vs brand new fibre stuff sums up to quite a bunch of money - humble local ISPs don't have all that crap and therefore can pass on the savings to customers.

Most broadband providers work with overbooking / contention ratios, so if you sell 100/100mbit you buy 20:1 to 50:1 less from the upstream provider. Overbooking ratios for consumer internet can be between for example 20:1 to 50:1. That means for 20mbit of bandwith to consumers you buy 1 mbit of bandwidth from a upstream provider.

Buying one megabit of uplink at current market rate is typically less than a dollar from upstream providers.

You can buy commercial Internet uplink and link up your neighbours for cheaper than broadband ratios. Digging fibre in the ground is fairly expensive but gives more stable connection and most bandwidth. A cheaper route is to go Wifi mesh networking but on normal wifi access points one radio per access point you get halving of bandwidth for each mesh hop. If you go open source mesh with 3 radios per AP you can get better bandwidth.
