If it were just individuals doing it, maybe it would've been somewhat digestible. But it's a pity that sometimes even trillion-dollar companies do it.

Pre-LLM days, the doers were atleast aware of their copy/clone/wrapper, but now it's happening unintentionally when LLMs give out modified versions of someone else's code without binding to its license, because AFAIK LLMs do not automatically add licensing details of libraries used inside their outputted code, or do they?
