All of those things are illegal in the country where Bandcamp operates. I think we customers already care to the extent that we ought to, and beyond that we should only insist that legal process be followed.

If we don't care about the employees, who does?
If we care only under certain circumstances, where is the limit?
Union busting, unpaid overtime, forced labor?
