Ethereum is free because there is no central authority to which you must make a payment. You only pay a transaction fee. It's a distributed network, so a node processes each transaction, and you don't know who owns it. The nodes are randomly selected. If it successfully mines your transaction, the transaction fee is awarded to that node.
