No, that was the original claim. That you need the miners to agree. They are the ones that hold the computing power.
The claim I responded to says that in addition to this, you also need the majority of the "nodes", which are just computers that do no work and just forward transactions. This is incorrect, you do not need their help. It is easier if you have it, but you do not need it.
The nodes are what actually enforce the rules. If you send out a transaction with 25M coins in, nodes won't broadcast that transaction and it doesn't make it to the blockchain.
