Ok. But why would someone do this? I hate to sound conspiratorial but an AI company aligned actor makes more sense.

Malign actors seek to poison open-source with backdoors. They wish to steal credentials and money, monitor movements, install backdoors for botnets, etc.

Yup. And if they can normalize AI contributions with operations like these (doesn't seem to be going that well) they can eventually get the humans to slip up in review and add something because we at some point started trusting that their work was solid.
