When other people start doing that to other teams at work, other people in open source, other people in professional settings, etc it becomes a problem for various reasons. The idea that I'm gonna gift you with a 75k lines of python to "just run it" and ask your agent to hack on it might be fine (who cares as you put it). Now scale that to 47 of such projects (a month)
They are trying to get in every opensource projects, increasing the burden of maintainers. And once a ban is announced, they’re here protesting.
