Maybe we care about where something comes from, but we don't have the will to care about everything? (also, never meet your heroes comes to mind regarding the endless debate)

For example, I had never thought or cared where the trash can in my office came from. I forgot where I bought it from. Now that I'm thinking about it, I'm a little curious, but is it worth knowing? If I knew the designer of the trash can was a bad person, should I get get a new one and make sure the designer of that trash can is a good person?

I think logically and ethically yes, but I'm not willing to spend my time on this.

It's an extreme example, but I think the same applies to music, art, movies, etc, just to a lesser degree for people who claim they care more about the outcome than the human author.
