What?!? Bitcoin is not about voting. What do you think it is? Run your own node with your preferred rules, and that's what would be valid for you. Everyone sharing the same consensus rules would be "in consensus". That's all. There's no vote anywhere.

Nodes don’t “vote” In this context they matter to the extent the humans using them stop doing commerce with other network participants because of differences in the rules their nodes operate under. CashApp’s node is vastly more important than your node or mine for that matter because more humans rely on it to participate in the network. No one is implying any one node has more influence within the network than others. But as I pointed out, in the real world some nodes absolutely have more power, influence, and importance. We live in the physical world not in the code. Politics matter.
