Your premise seems to have little regard for scale. Yes people are shitty but how they allocate the resources given to them matters.
Your argument here is nebulous fictional supposed evil people are probably doing bad things which allows you the comfort of not figuring out who is doing little harm vs a lot of harm because under your framework it doesn’t matter. As long as any actors real or imaginary in the system are bad you are absolved from participating in trying to alter market forces in your own small way.
To others on here there’s a difference between someone who did a shitty thing or has a shitty belief and one whom is tied into a direct political action block they are funding off of the proceeds they get from licencing their intellectual property to video-games and HBO series they are producing right now. This isn’t really about reading the books you already own or the DVDs you already have. It’s about killing the public interest that is keeping the author relevant and making her megaphone louder and the lawyers she funds to fight Supreme Court cases to disenfranchise trans people richer.
Scale is the main consideration.
The short answer is it’s not books. It’s mostly licencing deals in the form of video games and merchandise… However HBO is about to put forward a new series that JKR will have executive control and an executive sized pay check for.
It’s the “well it already exists and licencing deals are already paid, might as well watch it/play it/own it” that keeps the whole engine rolling on. Every time there’s a little bit of advocacy to disengage from the fandom it is always spun as “too late” or focuses on the books or death of the author… But all that’s really required is ambivalence.
Inevitably the new HP thing will come out and whether or not trans people mention anything people will drag up the controversy, use the reminder to brigade the spaces trans people connect online, try and goad their trans coworker for a commentary and set off yet another flurry of right wing backlash that makes elevating the franchise a patriotic duty to “stick it to the moralizing trans people to show them who is boss”. All of this causes more cultural pressure on a population already underwater with being chased out of the public sphere but it will be framed as a just retaliation for a perceived slight.
It’s a song and dance that will continue ad infinitum as long as it’s profitable because appearantly nostalgia is worth turning a blind eye to the where the money goes.
