Imagine OpenAI is required by law to list their weights on huggingface. The occasional nerd with enough GPUs can now self host.
How does this solve any tangible problems with LLMs regurgitating someone else's work?
I'm not the OP, but here's my from-the-hip answer: if weights are public, building and operating an LLM is no longer a business plan in and of itself, as anyone could operate the same LLM. Therefore companies like OpenAI will be disincentivized from simply redirecting web traffic to their own site.
The AI goldrush has proven that intellectual property laws are null and void. Money is all that matters.
Indeed they never really mattered. They were a tool for large corporations to make money and they will go away if they can no longer serve such purpose. Anyone that thought there was a real moral or ethical basis to "intellectual property" laws fell for propaganda and got scammed as a result.
The problem here is enforcement.
It's well known that AI companies simply pirated content in order to train their models. No amount of license really helps in that scenario.
