So you don’t care about the inequalities that it can create or reinforce as a result? Since it wasn’t the intention of the creators, just a limitation of their resources, we should accept and don’t complain if it generates undesired externalities?
I think even this is too generous. These “detectors” are claiming to do something which is impossible from a technical sense. You can’t calculate perplexity without knowing the prior probability distribution, and you can’t know that without knowing which model was used. They’re playing a dangerous game where the consequences for being wrong (which will be borne by innocent 3rd parties) can be extremely dire.
Even election polls correct bias due to underrepresented populations among the responders.
