Secondly, on the page https://nix.dev/contributing/how-to-contribute they say "Currently the focus is on funding in-person events to share knowledge and grow the community of developers proficient with Nix. With enough budget, it would be possible to pay for ongoing maintenance and development of critical infrastructure and code – demanding work that we cannot expect to be done by volunteers indefinitely." So that means they want a centralized team.
Third there's an active topic there which shows clearly that the team behind nixos is centralized and corrupt and politically driven: https://discourse.nixos.org/t/why-was-jon-ringer-banned-from...
This whole project smells like a honey pot. Centralized = bad.
