I'm not sure how anyone familiar with open-source communities would fail to predict the backlash though. They really should have forked the repository and switched the deployments over to their downstream fork (if I'm right about the root cause here).
(I'm mostly thinking in terms of supply-chain attacks, like this one: https://blog.rubygems.org/2025/08/25/rubygems-security-respo...)
and I doubt you could ever get negligence to stick, given you are downloading code from some website and running it, on your own accord, entirely unprompted
(but IANAL)
