Blockstream, of which Maxwell is an officer of, stands to profit from Bitcoin becoming a settlement layer. Settlement layer solutions are literally Blockstream's only products.
Do you have any proof to back up that claim?
From what I understand, the only products blockstream currently has are blockchain tech for banks, such as "confidential assets" and the work they did on IBM and Intel's "hyperledger".
They did not develop any lightning implementation, nor did they state they planned to run a lightning hub, and it doesn't make much sense for them to run one as the best businesses to run LN hubs are companies like coinbase and bitpay who already have a large base of users and merchants and are already doing offchain payments.
