Bach was, after all, writing for the instrument he knew.
I've been told that there are modern orchestras that avoid performing Bach specifically because critic snobs lambaste them for not doing it on period instruments with historic bowing, etc. etc. etc. so it's just not worth the effort. That is truly sad to hear.
They are imposing their own sound ethic on the music, drawn from 20th-century ideals rather than 18th-century ones, and and searching for historical support for their ideas after the fact.
