I’d make backups of my purchases and share them with love for preservation and promotion of their authors hard work. “Piracy” was already shown to increase sales, not reduce them. If you really want to do something against an artist you no longer align with, dont consume their products. Don’t purchase, don’t download and don’t share their stuff. Just look around for other artists you do align with, get hooked to their art and support them instead.
That’s a huge oversimplification. UX design and a careful selection of settings and features, for instance, have a big role in that regard. It’s not what you prohibit but what you incentivize too.
