I've said it before, but the whole property angle of this is a red herring to frame all the discussion around AI on an issue that benefits large property holders and any corporation that claims ownership over its users content, and away from its effects on labor and the harm that generative AI enables in both volume and nature of material.
That is, it focuses all the ethics on "first of all, property is sacred and ideas can be owned and made exclusive to companies that can buy them, and second the gravest sin is infringing upon property by daring to look at an idea in a manner you have not expressly paid for" which is all 100% bullshit in every way and is a distraction from the fact that owning tons of property doesn't make generative AI ok.
The correct angle should be forcing all generative AI and its products to be public domain, as well as anything incorporating them. Completely kill its commercial and industrial value to corporations when they can no longer own it exclusively nor use it to eliminate labor because they cannot own anything it produces.
