Ironically, for old stuff at least, Piracy is the only way it's reliably preserved. Even if you do want to buy it new to support the creators, oft-times you can't. It's because I can't buy it that I turn to piracy. Not just for old games, but sometimes old comics and manga too. Occasionally Anime that's no longer licensed or available.
Plus, it's only going to get worse now, with Streaming services and online platforms delisting anything even that might not make a profit because they don't want to pay residuals. I'm not big on pirating new releases, but that's because I think we should support artists. I also think we should call for the creators to be paid more of the profit share vs. the money people at the top who seem to do nothing but fire people and shoot down good ideas to try to make everything the same carbon copy live service.
I also don't have to pirate new stuff, because it'll old stuff on sale at half price (or less) soon enough, and with all the bugs fixed and the features added the way it should have been at launch. My backlog is so huge that I won't have time to go through it anyway before I die. So there's another reason I don't care much about new games. If I'm still interested in them a year or more later when they're on sale and fixed up, I'll buy it then.
As for stuff like Anime and Manga. Anime subscriptions are surprisingly cheap, and so are monthly manga subs if you know where to look. Viz's Shounen Jump ($3) Vizmanga ($2), Azuki.co ($5), Mangamo (also $5 last I checked)... so long as you only subscribe to one at a time and rotate, you'll probably never run out, and it's a lot cheaper than buying it one volume at a time $10 each or whatever.
