Bill Ackman?! Who on earth cares enough about _Bill Ackman_ to white-knight him with Twitter bans? Up until you mentioned him I'd completely forgotten he even existed.
If this conflagration continues ... it may have a positive effect on reducing plagiarism. But since LLMs can easily reword text, the plagiarism wars are more about the past than the future. Because now the plagiarism of concepts rather than phrases is cheap and easy and far less detectable.
Perhaps plagiarism review can move to detection of shared sequences of concepts rather than words.
