Well pointed, it is a good method to get back some sats! Territory owners all deserve it, because to pay 100k sats monthly it is not a small amount!
Hopefullt very soon this will be an automatizes preocess (based on a smart contract), and territory owners will receive their sats automatically for pinned posts (this mean that who want to make her / him post to pin, just pay the "pinning fee", and this will arrive in the wallet of territory owner).
