What does that mean for you?
The network fee is part of the transaction. It helps pay for including that transaction in the shared record. There is no central Bitcoin company collecting all network fees.
An operator can also charge for its own service. If a withdrawal screen shows a fee, read the terms rather than assuming every part of that charge goes to a miner.
Can you picture an example?
Imagine an account charges a withdrawal fee before sending your payment. The operator's charge and the fee in the network transaction need not be the same amount. The label on an account screen does not explain that split by itself.
What should you remember?
Separate what leaves your balance, what reaches the recipient and what the fee covers. A payment receipt or service statement should be read in that context. Never send recovery words to someone claiming they need them to collect a fee.
