I’d say they are equally absurd.
I wouldn’t say these creators will always have a line of speculators/dealers/ flippers though. I’ve noticed over the last couple years quite a few people walking away from the creators who are upcharging like this, and rightfully so.
I’ve personally also cut ties and no longer support several creators who do so. Many of them I’ll never support again, no matter how appealing the book may be.
The solution really is to just boycott supporting them, and if an opportunity presents itself I recommend letting the creator know why, because the people whispering in their ears that are also profiting off of basically doing nothing are the voices that really need to be drowned out.
