EFF does some good stuff elsewhere, but I don't buy this. You can't just break this problem down to small steps and then show for each step how this is fine when considered in isolation, while ignoring the overall effects. Simple example from a different area to make the case (came up with this in 2 minutes so it's not perfect, but you can craft this out better):

Step 1: Writing an exploit is not a problem, because it's necessary that e.g., security researchers can do that.

Step 2: Sending a database request is not a problem, because if we forbid it the whole internet will break

Step 3: Receiving freely available data from a database is not a problem, because otherwise the internet will break

Conclusion: We can't say that hacking into someone else's database is a problem.

What is especially telling about the "AI" "art" case: The major companies in the field are massively restrictive about copyright elsewhere, as long as it's the product of their own valuable time (or stuff they bought). But if it's someone else's work, apparently it's not so important to consider their take on copyright, because it's freely available online so "it's their own fault to upload it lol".

Another issue is the chilling effect: I for one have become more cautious sharing some of my work on the internet, specifically because I don't want it to be fed into "AI"s. I want to share it with other humans, but not with exploitative corporations. Do you know a way for me to achieve this goal (sharing with humans but not "AI") in today's internet? I don't see a solution currently. So the EFF's take on this prevents people (me) from freely sharing their stuff with everyone, which would otherwise be something they would encourage and I would like to do.
