I doubt anyone cares at all. You get a fair amount of snobs who will lock their files up and ask for specific trades or for bandcamp vouchers in exchange for access to what they have but I don't converse with those types personally. If I see them I usually block them from downloading anything of mine out of principle because I can't stand that attitude.
However everyone else I've interacted with there are more concerned about the quality and don't really care of origin or anything like that.
