Another example of greedy Bitcoiners, regardless of the date that they've joined the ecosystem, are those (see XT, Classic, BU, Bitcoin ABC) that want to centralize the network for a bit more throughput.
It really isn't that simple if you choose to embrace all aspects of Bitcoin. If you abide by the ethos of open source and permissionlessness, you can't then begrudge other developers creating their own clients, even when you disagree with what their goal might be. There's also the issue of
developer centralisation and trustlessness, which I've commented on before. It isn't black and white. You can't see other clients as a threat to decentralisation and trustlessness if not having an alternative would result in relying on a different kind of centralisation and trust. Developers can't be all-powerful and you can't force everyone to run the code you prefer. That's not Bitcoin.
