I think there’s a big difference in writing books as in literature, and writing school books with the purpose of passing on knowledge.
For me, knowledge is 100% fine to pirate, while literature is okay, but buy the ones that you liked to support the writer. Just like games/movies.
I felt the same, but there’s just things that’s forever popular. I don’t mind not seeding, if there’s already 200+ doing it.
But for all the niche things, and for personal favorites, I’ll seed for a loooong time.
