> is a result of unencumbered, massive, law-breaking, right-violating copyright infringement Why? Copyright covers expression not information, AIs can learn information from any source regardless of copyright. They should just not regurgitate copyrighted content, that's all. And much of what organic content is online is common knowledge, thus can't be copyright-controlled.
Copyright is for things that are the result of human creativity. If the weights come from running an algorithm on a training set (that one does not have a copyright to) then how can the weights then be copyrightable? They might be a derivative work, but that just means they infringe copyright, not that they are copyrightable themselves.
The US has the "threshold of originality" as its principle. Under that doctrine, it requires some human (and this has been emphasized many times over the years) originality in order for something to be copyrighted. It's a low bar for how original it needs to be, but it must be human (monkeys taking selfies are not human).

In England, the doctrine is "sweat of the brow" instead.

> Under a "sweat of the brow" doctrine, the creator of a work, even if it is completely unoriginal, is entitled to have that effort and expense protected; no one else may use such a work without permission, but must instead recreate the work by independent research or effort.
The definitive case for this in the US that set the two apart is Feist Publications, Inc., v. Rural Telephone Service Co. ( https://en.wikipedia.org/wiki/Feist_Publications,_Inc.,_v._R.... ) where it was deemed that a telephone directory is not copyrightable in the US as there is no originality in it... but under the sweat of the brow doctrine it would have been.
So the "[c]opyright is for things that are the result of human creativity" gets an "it depends" and it would be curious to see if companies that are firmly in the "models are valuable" camp go to the UK for what I believe would be a more favorable copyright protection.
... However there are other IP laws around trade secrets that may be better for it in the US (I'm not as familiar in that domain - I would be curious to find out).
