I just started pirating again in the last couple of months after basically not pirating for years. Now fuck corporations lol.
I pirate books for a few reasons, first is because knowledge should be free, second is because buying books gets expensive real quick and third because I can't find everything I want to buy, sometimes pirating is the only way to get it. I like to have it physically when possible, tho.
Entertainment (Series, Anime, Cartoons, Movies) I pirate because I'm sick of being a second class citizen of nearly every streaming service just because I'm a Linux user. I can watch netflix at 1080p with an extension on Firefox, and Crunchyroll doesn't limit me in any way, but everything else is 720p or lower. By pirating, I even have 4k available. Also, fuck streaming prices and fuck netflix for charging extra for sharing an account.
Software I don't pirate because I prefer to use FOSS and in the case of games I don't really wanna gamble if I'll get a malware or not. Besides, I have a huge respect for the medium and I buy a game whenever I can.
For music Spotify and Youtube is too convenient, I only pay for Spotify, tho. Revanced for Youtube on mobile and ublock origin + sponsorblock + return youtube deslikes on desktop is great.
Besides all that, everyone should have access to knowledge and entertainment, it's 100% justified for people to pirate, specially those that can't afford it.
Also, have you ever noticed that you have felt that the value of a product has decreased just because you didn't pay for it, thus you are less interested to read it? i.e., had you paid for the book, you would have more likely read that book.
When I used to pirate heavily a decade ago yeah, today not really, buying or not my ADHD is so bad I can't get through easily anyway lol.
