Very true. Like refueling your car probably help slavery in the middle east a tiny bit, buying any clothes funds sweatshops somewhere and eating chocolate also enables slavery where ever. Rowling is a tiny drop in the ocean of all the bad shit everyone are already passively funding.

There's zero ethical consumption in capitalism and boycotts of massive global brands like this are as effective as trying to empty the ocean with a bucket. If you want to enact real change then join a union, volenteer at a soup kitchen or do work for a political party you believe in.
