it's not public domain, it's copyrighted

what's the bet that the intention here was explicitly to attempt to strip the copyright

so it could be shoved on the corporate website without paying anyone

(the only actual real use of LLMs)

That's what's so disgusting here: it wasn't even about payment, it was about not having to attribute it to who created it. That's too much of a payment for MS, so they just take your stuff, run it through their white washing machine and call it a day.
