Bitcoin already is. Blockstream LLC employs a majority of core developers with commit access, and thus can effectively hold the protocol ransom for profit, and they have been doing so for over a year now. Good luck ever getting a fee-less transaction accepted, and even at "standard" fee rates your transaction may not be accepted into a block for hours due to the backlog because they have intentionally kept the maximum block size at 1MB, intending to sell for-profit centralized corporate services that "guarantee" rapid block acceptance on their own lightning platform.
