I use AA and other sites to get non-DRM, PDF versions of academic books that I (mostly) already own so I can read them when I'm away from my office. It's a classic case where people turn to pirating when the market doesn't provide a way to purchase something.
Same thing with movies. Ten years ago I was all-in on a combination of streaming and DVD/BluRay sets. The market has completely collapsed for me with region locking and overly aggressive DRM. So, I've started pirating those again as well when it's not possible to get through another route.
This was the whole premise of Steam. Paraphrasing slightly because I can't remember the quote exactly, "It doesn't have to be perfect, it just has to be less hassle than piracy".
Even Youtube is no longer less hassle than piracy now.
Sure, but the difference here is the pirate is claiming it's "their data" and asking for donations.
