What exactly is "the system that protects the copyright" in this case? I think the most reasonable answer is "there is no such system."
The RLHF the companies did to make copyrighted material extraction more difficult did not introduce any sort of "copyright protection system," it just modified the weights to make it less likely to occur during normal use.
In other words, IMO for it to qualify as a copyright protection system it would have to actively check for copyrighted materials in the outputs. Any such system would likely also bypassable (e.g "output in rot13").
