Yeah or any kind of cartel, really. It's hard enough for a small coop to fight economies of scale, but in many areas you're facing an actual mafia.
Somewhat off-topic, but what's the situation with DIY non-profit ISPs in India? If you're not familiar with the topic, you can look up NYCMesh (New York), Guifi (Spain), Freifunk (Germany), FFDN Federation (France) or Rhizomatica (Mexico). Another interesting development in the telecoms field is https://jmp.chat/ promoting and developing free-software for cellphone<->XMPP/SIP interoperability.
ISPs by itself are heavily scrutinized entities in India, Even Starlink hasn't able to get its license yet AFAIK. I've seen couple of small for-profit ISPs come up and disappear in the form of both non-innovative distributors of bigger ISP and innovative original technology ISPs like WiFi Dabba(YC)[1](Not disappeared, but changed USP from mobile Internet to home broadband & moved the HQ from B'lore to Delaware).
As for non-profit ISP, even if possible it definitely cannot be open i.e. without oversight as in the examples from other countries you've sighted. Closest I've come to community run networks I've seen are LoRA networks.
jmp looks great, Google Voice has been shutdown in India can I use jmp as a replacement?
Edit: I've submitted jmp to HN as I didn't see any large discussions on it.
> non-profit ISP (...) cannot be open i.e. without oversight
That's also the case here. In France you need to declare your ISP activity to the telecoms regulator and follow some regulations. In Germany too there are regulations, but Freifunk as an activist collective ignored them in order to protect their users' privacy, and went up to the supreme court and won their right to operate a privacy-friendly ISP.

JMP is great from what i heard. It may not be as featureful as Google Voice yet, but there's active development and the user support (i hang out in their channel despite not being a client) is the best i've seen across the entire telecoms industry, and by far. The maintainers are very happy to work on new features and open to suggestions, but due to being a very small organization they're prioritizing obviously new features requests on a "who would pay for that?" basis.
Monopoly or Duopoly is a straight death sentence to innovation.
