it is also a statement making social commentary about how someone can consume a piece of media without being supportive of the author and their actions as a private individual

That's true, unless you are buying the products or watching the shows on a service, which would be supportive of the author.

It absolutely is either/or

Stopped reading because that is so blatantly wrong, trying thinking harder please.

It isn’t the consumer’s fault that the product they enjoy is tangentially used to fund oppressive organizations

That's also true, but it is the consumer's fault if they continue to support products that are used to fund oppressive organizations, particularly if it isn't a necessity, and particularly particularly if they are quite well informed about the issue.

Literally every single thing you consume under capitalism contributes to the oppression of a marginalized person

Yes, but some things are essential to living, but even in those cases the consumer can STILL vote with their wallet. I repeat, "no ethical consumption under capitalism" is not an excuse to make the choice to support unethical organizations when there are more ethical alternatives.

If someone told me they specifically bought slave labor produced goods because they are always cheaper, they would still be wrong even though everything in our system exploits someone somewhere, because there is always a choice between lesser evils.

You can bitch about the individual all you want, and I’ll continue to call everyone who does a shortsighted, myopic fool.

Sorry you're so triggered that people are rightfully judging you for choosing your little fandom over human rights, but it's a choice you are actively making. Stop being a pussy and hiding behind excuses, you support J.K. Rowling because you want to.
