This is very interesting for me to think about, since I have so many issues with proprietary technology in general. An LLM copying the code from thousands of proprietary projects is kind of an interesting loophole considering that it would be difficult for any of the individual businesses to prove that their proprietary code was infringed unless the LLM does copy and paste the code exactly. That could cause major changes in the tech industry which I'm not able to predict. Optimally I would like technological development more in the hands of people than behind legal barriers such as with Open Source code and I am not a programmer, so take my musings with a grain of salt.
