This doesn't seem egregious enough to fire the customer.
This is somebody spending their free time on code they enjoy and then putting the result online.
The reason businesses are careful about which customers they fire is because they want to keep having customers. Open source maintainers have no reason to deal with that shit.
Again: we are talking about rsync here. This new methodology being used this year seems to be associated with a regression (ie: Data loss since this is rsync after all....) that likely wouldn't have happened any other year.
Or at least: the regressions at play are consisting of thousands of lines of changes that was only navigated by Claude later down in the discussion.
We are reaching the point of AI developed code that requires AI itself to analyze. One step at a time. It's right for the open source customers who are used to understanding changes and smaller patches than this.
