The reality is that people hate the corporations using creative peoples works to try and make their jobs basically obsolete and they grab onto anything to fight against it, even if it's a bit of a stretch.
I'd hate a world lacking real human creativity.
You have to opt-out. I got an email from meta with a link to the form. Doesn't seem to matter really what you write. It got approved in less than a minute for me. I think they purposfully made it look like it's more work than it's worth.
It's not really about the AI content being a violation or not though is it. It's more about a corporation using copyrighted content without permission to make their product better.
And some automation I have no problems with. However, if corporations would rather use AI than hire creatives, the creatives will have to look for other work and likely won't have a space to express their creativity, not at work nor during leisure time (no time, exhaustion, etc.). Something should be done so it doesn't go there. Preemptively. Not after everything's gone to shit. I don't see the people defending AI from the copyright stuff even acknowledging the issue. Holding up the copyright card, currently, is the easiest way to try an avoid this happening.
