Is it surprising? The bulk of their work is largely derived from existing works themselves, nothing original, everything probabilistically paraphrased and then post-trained by lowly-paid, ESL workers resulting in the really annoying, mic-droppy writing output. It will never be original, it will never be new, it will always only be derivative.

They have not made anything revolutionary, they have only ever made evolutionary derivatives of medium-to-high quality with no accreditation or financial support for the original authors (at least not without being forced into a class-action over it).
