Open weight models cannot do this, they do not have any funding. If you demand this, you are just demanding that there will never be any open models, that proprietary AI models controlled by massive trillion dollar corporations will be the only models available, and frankly the cure is worse than the disease.
It’s also impractical, like closing the gate after the horses have already gone. Open-weight, unethically trained models are already out there. They are not going away. You cannot put the genie back in the bottle. They will never earn any money, so they will never be able to compensate for the training that was done to create them, unless you consider the fact that they exist, and they are open to anybody, as at least some measure of compensation.
It’s not enough compensation, but it is something. The training was certainly unethical, but so is an economic system that requires intellectual property to be transactional. Why fix one unethical thing while keeping and reinforcing another?
The only sensible and reasonable way to resolve the issue in the long term is for significant government support and patronage of the arts and content creators (and ideally all people) to be established. People who do this for a living are providing valuable service to all of humanity and that deserves to be recognized not by transactional, metered capitalism that defines each piece of art or content in terms of its raw economic value (a system easily and frequently corrupted anyway if you look at the prevalence of theft, forgery, fraud and money-laundering in the high art world), but by guaranteeing a comfortable and dignified life that allows creative people to freely create the art or other works they love and feel passionate about without worrying that they’re going to starve to death or be forced into a dead-end job if they’re not economically successful.

I think there is some confusion and potential for misinformation here. SSH in key-only mode (common configuration) protects you from this problem, because it never accepts or even attempts any passwords at all, regardless of length. SSH in password-allowed mode with at least one user who might be a key-only USER by merit of having a password hash of “*” (not a valid password hash) is a prerequisite for this. That is a very different and very common thing, as most systems come with at least one key-only user by default. But gaining access to that user with an incorrect, invalid password still requires having passwords enabled at all.
To be clear: Password access enabled is a prerequisite, and by extension, password access disabled (key-only) prevents this.
The website you linked clearly defines that all of these conditions must be true for you to be vulnerable, and as far as I can tell, it is exactly correct:
The * account which they suggest potentially being “key only” is the prerequisite you are talking about, but having SSH itself key-only (which is best practice anyway) prevents the attack entirely.
