I pirate metric shitloads of movies and series. I don't pirate music or games (much).
I watch maybe 5-10% of what I download. That's probably true for the games I buy as well.
The reason is part convenience. I probably listen to royalty free 95% music of the time, but for the other occasions Spotify has anything and everything I want to listen to. I can't beat that library.
I game on Linux, the Switch and old retro computers. The old retro computers have all pirated games on them, but for Linux and Switch I buy my stuff on the Nintendo shop and Steam. They have everything and it just works.
The video streaming services of today have also taught me that they will pull licenses. When Netflix had a big library I stuck mostly to that, but today it feels like all the good content has been pulled and they mostly just have Netflix originals. So Hollywood has taught me that If I want to watch something, I shouldn't rely on it being available on my streaming service of choice in the future. I'm not going to subscribe to a dozen streaming services just for the odd chance that I want to watch something particular. I'm going to have my own plex server with everything I might want to watch.
The one show that would make me consider getting a second streaming subscription just to support it is Futurama. But of course, Hulu is not available in my region.. so, yarr.
