    An identity-on-objects functor is not a functor in the same sense that Cat is not the 1-category of categories and functors.

    As such, I don’t think it belongs as an example on this page, since it depends on an uncommon interpretation of the terminology.

    remove identity-on-objects functor, which is not at all the kind of thing this page is describing.
