You two are conflating scientific discoveries with products. Gravity existed before Newton discovered it. He didn't create it. Likewise, it is fine to consider the theory of relativity without going into Einstein's childhood or upbringing or other personal traits of his.

It is, however, absolutely essential to take into account the person behind a product when evaluating a product. You would never write an essay on the film stylings of Stanley Kubrick or Roman Polanski without fully considering their backgrounds and personality quirks. You would certainly never write about a work of classic literature without first taking into account the context of when the book was written, what life experiences the author had, or what inspired the author to write such a book.

Products like TempleOS should be treated the same.
