They don’t even have to be intentionally built in. Anything that generates unnecessary work for FOSS volunteers is a win for proprietary software companies.

Even an easy to use and well-built tool that produces good results would result in mailing list and bug report noise simply because people like to contribute. If we set aside those who are just trying to pad their resume with open source contributions and bad actors trying disrupt FOSS projects, we’re still left with a lot of well-intentioned, mostly inexperienced devs generating duplicate and/or invalid reports and requests.

Since the current state of AI tools certainly does not produce consistently good results, I don’t think organizations that are hostile to FOSS projects actually need to do anything at all for them to be disruptive. Just make their shitty tools accessible and other people will significantly contribute to maintainer burnout without even intending to.
