It goes much further than that. They use LLMs to create code for them and then they claim ownership to the code.

I think that is one of the main reasons there is so much pushback against this, a lot of people are now addicted to their stream of washed code and want to claim ownership over what is essentially a derived work. The key then becomes 'if a work could not have been written by the author that claims it does that claim survive'. I think it should not but there is plenty of disagreement on this.
