While I honestly agree with the theme, the difference is that Meta wasn't looking to share them with others, at least not in their original form.

I can download terabytes of content to train my AI (hypothetically) and I don't think anyone but my ISP (and not because of IP issues, more for being a disproportionate consumer of their resources) would notice me, including and whatever industry I was using content from. It's the sharing that incurs the real damages.

Admittedly, Generative AIs are basically going to "share" the content (with someone, likely for a fee) as well but not in its original form.
