I'm glad I came over here way before the sh*t storm years ago. Also
Apparently there's a report saying these pirate sites causes their publishers to lose 300 billion yen. So they decided to shut them down. LMAO
Do they not realize those people wouldn't even bother considering buying from these publishers to begin with. Not to mention, these "pirate" sites actually serve as an entry point for fans all over the world. It acts as a free advertisements for these publishers that they would otherwise have to pay for.
They aren't losing money from these sites, they are going to lose more money without these sites, most specially when the current series from those publishers' ends, because their new and obscure series which normally gets discovered in the internet (thanks to these pirates sites) are no longer gonna be available for the rest of the world. If they want it known, they are gonna have to pay to make it popular enough to sell. Heck I pay for One Piece merchandise even though I was just initially a freaking pirate( I still pirate a lot of stuff, but I support if I actually like the series, like buying CD soundtracks specially if they have good music, but I mostly discover those series from pirate sites)
For example, most of the series getting serialized and animated were web novels, which are free to read. Imagine web novels from obscure authors are paid to read, barely anyone would give a sh*t checking those novels, specially with how much their authors use cliche genre's, setting, characters and stuff that they have so much generic and trash stories out there.
If anything, the yearly increasing revenue(yeah big shit, they are actually earning more with every year passing) from the anime/manga industry is likely going to take a hit for the coming years with their increasingly tightening hold from piracy.
Anyway, I don't wanna get too heated in an argument about piracy and stuff, but if all free manga/anime hosting sites shuts down, a lot of people wouldn't be able to discover obscure series like "I reincarnated as a vending machine" or some other obscure sh*t people read for kicks.
