By collusion I mean in the election process to get NN positions, not the notarisation process itself, and when I say bad for decentralisation I'm not talking about mining KMD itself, but more how many independent separate entities become NN, and the extent to which co-operation between them makes them appear to operate as a single dev team sponsored NN system that employs 64 sys admin operators, or at least has potential for that perception to grow.
I strongly disagree with "Who does it is pretty irrelevant" - if you really believe that why not stick with PayPal & Visa, why not just have one entity responsible for running 64 global NN and let that entity employ 64 contractors?
Crypto users are searching for projects that are decentralized, trustless, competitive, adversarial, and the assumption from nearly everyone in this space is 95% of projects are scams designed by insiders to enrich themselves.
Don't get me wrong, I have been supporting komodo for years and love the tech, but I really hope these elections for NN become super competitive and hard fought.
Still early days with the elections and candidate numbers aren't much greater than available spots so there's not much benefit from competing with other candidates yet, but that will come in time as kmd gets more attention with mature tech. This year is more about cooperation and If you follow discord it's great to see experienced NN helping new guys, that's what we need most now, 64 reliable nodes!
When the notary income becomes significant and candidates increase we will see more competitive behaviour, and I agree that's good for decentralisation, but for this election it's not a problem imo
