GitHub is to agents what StackOverflow was to developers back in the day (in a meme kinda way).
More seriously, I'm curious if you checked on the licensing of said codebases, were they permissive or strong copyleft?
Lolol nobody is checking that shit. Do most people prompting AIs even understanf what copyleft is?
Very few licenses allow you to copy code verbatim without acknowledgement.
