I’m in the camp of, “Not currently, but planning on it.”

Correct there is no voting, but all full nodes must validate that a block follows the rule set. Otherwise the block will be rejected. It requires both miners and full nodes to create PoW consensus.

And yes the node also gives one a client to validate stuff for oneself. But that’s not it’s primary role in the network.

Seems that he fails to mention bitcoin has 2 types of nodes. One of which is non-centralizing.

Edit:
Bitcoin’s miners do not provide consensus, it’s validation nodes do.

Idk, seems like he’s overlooked a major portion of why bitcoin works.
