You are probably right, it’s just funny that there’s a public list saying „don’t go there“ which kinda acts like a „forbidden books“ list making it more interesting.
So blocks like these will definitely discourage more Average Joes from low hanging fruit piracy and keep them as law-abiding paying customers rather than turning them into "hackers".
But as an Austrian myself, piracy was alive and well when I was in the age group where that usually happens and many "regular" people used free streaming sites when kino.to and others were still popular.
The libraries of streaming services are tiny compared to international offerings and some don't even offer anything in Austria at all because it's a small market.
Pirating is still alive and well, not necessarily because people can't/don't want to afford the alternatives, but because they just aren't as convenient.
