Chainlink is a permissionless protocol for building oracle networks, Chainlink Labs builds oracle network services on top of that protocol, companies then pay for the integration, maintenance, and usage of those oracle network services
Oracle networks are not autonomous “set and forget” infrastructure like blockchains, their purpose is to generate consensus about the messy subjective real world which requires continuous monitoring, upgrades, and ability to resolve issues on the order of minutes
Who do you think is waking up at 3AM to resolve a data feed issue because a blockchain decided to do a hard fork without giving anyone else notice again
We are talking about real world mission critical infrastructure securing $77B and that requires SLAs and someone to call when something breaks
People actually depend on chainlink working, this is not ghost chain #57269263748 where nobody notices if something breaks
