Dave, by the sounds of it was a kind and gracious friend to Daphne and this was corroborated by her family. He offered her to open for him in a club as well, a great opportunity given his tenure as a comedian. In addition, upon hearing of her passing, setup a trust for her daughter.
The twitter mob on the other hand tried to have her cancelled after she defended him because she knew that he had no ill-intent.
In my opinion, the 1K employees who are walking are doing so on the flimsiest of moral foundations. Dave has done more for Daphne and her family than any of the 1K employees or the twitter mob ever will. Moral outrage is not generous or kind to anyone, period.
