Recently, there has been a Twitter pogrom about Shueisha's actions. This is another act of Japanese action to limit anime manga piracy, the use of images by internet users, and such things. Shinzo Abe, the former Prime Minister of Japan, spoke about this "problem" many times. I found out about the case from fp Dragonworld and I encourage you to like it if you are DB fans. They provide a lot of substantive information. This site had a problem a year ago and they had to start the fan page again.

Why did I put the word "problem" in quotation marks? Because some of the arguments (I would even say many) and seeing it as a gigantic problem is nonsense that has little to do with reality. As I wrote several times in the texts on piracy, Contrary to what corporations say, it's not that one spiracon copy = one purchased copy. If something is readily available for download on the internet, most people just enjoy it and watch it. If it were not possible, they would simply do other things to fill up their free time, e.g. watch legal movies or TV series. This is confirmed by research conducted by the European Union. And before someone says that these studies could have been carried out, for example, on commission (like studies that tried to forcefully prove the many advantages of smoking, as happened decades ago in the USA) - even EU opponents say that what but their data is close to reality + methodology is good and substantial.
Moreover, were it not for piracy and web traffic, which is generated by every mention, discussion, uploading of any picture or video, many titles would not be so popular outside of Japan, and the Japanese could count mainly money coming from their domestic market. And there are a lot of those from abroad - license fees, more copies sold, the possibility of adapting to other media (games, movies, series). A simple example from our Polish backyard - JPF publishes those titles that are popular in the Polish M&A fandom. If enough people discuss a given title and it is popular, they spend it because there is a greater chance that it will sell well. Why? Because piracy drives popularity and therefore more copies are sold legally. Sure, a lot of people settle for illegal copies, but on the other hand, not everyone is dishonest and prefer to pay for the original. And yes, there is something like Crunchyroll, but that mainly affects the US market and maybe Western Europe. Poland and similar small markets are just an addition. Plus, Poles cannot watch anime as easily as Americans do due to the regional blockade.
Before anyone says that there are anime such as "Bleach", "Naruto", "One Piece", "Demon Slayer", "Jojo's Bizzare Adventure", "Attack on Titan" etc. I will conclude it immediately with one argument. Although these titles have been or are popular, they are in no way comparable to DB, "Pokemon", or to a lesser extent "Sailor Moon" and "Captain Tsubasa". This is not only because they are old titles, the so-called "classics", but above all because they appeared in the best possible time. There are times when the internet was not so popular (especially in our part of Europe), and we watched movies, series, etc. not on computers, but on the TV. I don't know what it was like abroad, but in Poland, there weren't many titles that would be interesting for people, suitably exotic (because people like something that is more difficult to access and different from what we see in our surroundings) and had other advantages. Back then, these anime were watched not only by children but also by some adults. Today a similar result is impossible to achieve. Why? Because there was less awareness of what anime is and there was an incomparably worse flow of information. Even if many people thought it was just "another stupid story for children," hardly any title causes so many kids to run home at a specific time (theirs or colleagues, in case our house was unable to watch the TV station). Even without the internet, the flow of information, as much awareness as now, it was impossible to simply ignore this global phenomenon. Even today, as demonstrated by the popularity of DBS in many countries around the world, you can easily find in almost every city at least one person from my or our parents' generation, who could better or worse summarize "Dragon Ball" or at least know who Goku and his friends are. It is similar with the adventures of Usagi Tsukino, Tsubasa Ozora, but as I mentioned, it is definitely a lesser phenomenon. If I had to give as an example something with comparable popularity, it would be "Harry Potter" or the previously mentioned "Pokemons".
In short, Japan wants to eat a cookie and have a cookie, and you just can't. Not to mention, they harm themselves in the long term. By not fighting piracy they also harm themselves, but as Netflix, Steam etc. shows these are effective ways to keep them to a minimum. Disney and Netflix don't care about piracy because they have channels to deliver their content to interested viewers. In a simple and cheap way.
