I have a question, in their whitepaper, HPB state:
Despite being heralded as the onset of decentralization, a fully decentralized blockchain
faces many infrastructure-breaking problems. Due to their uncontrolled nature, the
infrastructure itself may be subject to roadblocks such as hard forks from a divided voter
base, or cartels that may form to control the voter base. The dual-election model of HPB is the solution to balancing the benefits we seek from
decentralization, and a stable infrastructure. Although the issue of decentralization is at the
very least sensitive, and at most subjective, we believe we have found a good solution. With
four core principles, efficiency, transparency, accessibility, and inclusion, we are able to
bridge the gap between decentralization, and effectiveness.

How can I interpret this, that they think decentralization is not as optimal as centralized governance?
In your article you state they achieve true decentralization? Can you explain how that happens? Do they have a lot of autonomously operated nodes around the world?
