You don't solve a dystopia by adding more dystopian elements. Yes, some companies are scum and they should be rightfully targeted and taken down. But the way you do that is by targeting those scummy companies specifically, and creatives aren't the only industry suffering from them. There are broad spectrum legislatures to do so, such as income based equality (proportional taxing and fining), or further regulations. But you don't do that by changing fundamental rights every artists so far has enjoyed to learn their craft, but also made society what it is today. Your idea would KILL any scientific progress because all of it depends on either for profit businesses (Not per se the scummy ones) and the freedom to analyze works without a license (Something you seem to want to get rid of), in which the vast majority is computer driven. You are arguing in favor of taking a shot to the foot if it means "owning the ~~libs~~ big companies" when there are clearly better solutions, and guess what, we already have pretty bad luck getting those things passed as is.

And you think most artists and creatives don't see this? Most of us are honest about the fact of how we got to where we are, because we've learned how to create and grow our skill set this same way. By consuming (and so, analyzing) a lot of media, and looking a whole lot at other people making things. There's a reason "good artists copy, great artists steal" is such a known line, and I'd argue against it because I feel it frames even something like taking inspiration as theft, but it's the same argument people are making in reverse for AI.

But this whole conversation shouldn't be about the big companies, but about the small ones. If you're not in the industry you might just not know that AI is everywhere in small companies too. And they're not using the big companies if they can help it. There's open source AI that's free to download and use, that holds true to open information that everyone can benefit from. By pretending they don't exist and proposing an unreasonable ban on the means, denies those without the capital and ability to build their own (licensed) datasets in the future, while those with the means have no problem and can even leverage their own licenses far more efficiently than any small company or individuals could. And if AI does get too good to ignore, there will be the artists that learned how to use AI, forced to work for corporations, and the ones that don't and can't compete. So far it's only been optional since using AI well is actually quite hard, and only dumb CEOs would put any trust in it replacing a human. But it will speed up your workflow, and make certain tasks faster, but it doesn't replace it in large pieces unless you're really just making the most generic stuff ever for a living, like marketing material.

Never heard of Cara. I don't doubt it exists somewhere, but I'm wholly uninterested in it or putting any work I make there. I will fight tooth and nail for what I made to be mine and allowing me to profit off it, but I'm not going to argue and promote for taking away the freedom that allowed me to become who I am from others, and the freedom of people to make art in any way they like. The freedom of expression is sacred to me. I will support other more broad appealing and far more likely to succeed alternatives that will put these companies in their place, and anything sensible that doesn't also cause casualties elsewhere. But I'm not going to be in favor of being the "freedom of expression police" against my colleagues, and friends, or anyone for that matter, on what tools they can or cannot not use to funnel their creativity into. This is a downright insidious mentality in my eyes, and so far most people I've had a good talk about AI with have shared that distaste, while agreeing to it being abused by big companies.

Again, they can use whatever they want, but Nightshade (And Glaze) are not proven to be effective, in case you didn't know. They rely on misunderstandings, and hypothetically only work under extremely favorable situations, and assume the people collecting the dataset are really, really dumb. That's why I call it snake oil. It's not just me saying exactly this.
