It was something I didn’t have a good answer for either. I think ownership is a good criteria but then I was trying to figure out why it was to me. Since it’s passed to an individual, via salary, is it still “my money”?
Amount could have something to do, but it’s possible for a highly paid IC to donate quite a bit.
The one that is cut-and-dry for me is something like Chic-Fil-A. My money is going directly to their foundation, which is used against LGBTQ people, so that’s an immediate hard no.
