"This is fair use" is just their public defense, but obviously they have never given a thought about this when hoarding data, as shown by the modest 1.5B fine of Anthropic, which they can now write off as a normal business cost.

I am completely willing to accept that "this is fair use" for any company that publishes the LLM weights, i.e. the result of processing all the copyrighted work, because they have performed a public service with this.

But when the so-called "fair use" was a method to transform public data into private data that they guard and claim that any access to it would now be IP theft and which they use to obtain huge profits, that does not look like fair use to me.
