@menelmacil A lot of you are barking "I wish there was any way to support the author" once the way is provided, how many of you find excuses in it. It's very funny, to be frank. There is no right or wrong way, they own the English license to it, that's all there is to it.
Business is not a charity. Nobody is doing this out of sheer love they have for you. Neither is the author, Netflix, amazon prime, steam or mangatoon. Let's make that clear. They're all companies that have their minds set on profit. Does that mean you shouldn't support them? Fuck no. They legally own the license to do this series. If you want this series, and if you actually give a crap about supporting, which you clearly don't, otherwise you wouldn't be making excuses. Then you should be buying those paywalled chapters from them, or watching few seconds long ad to support.
That said, nobody here said that author licensed it. That said, different countries, have different laws and different ways about handling IP. What's true to one, might not be true to another, so I'm not going to go into that to avoid confusing you further.
What deals they exactly make, it's between them and the creators. And if the creators get screwed by the deal, that will still net them more $ than you reading on Mangadex.
Splitting of the chapters is a common practice for literally every single publisher in China. Which is not something I'm fond of, but, in order to keep the series up to date with China, it's something that's necessary to adapt.
Legally, no matter who owns the license, and no matter their practices, you should still be buying, because they legally have the rights to do it. And they're not small. They have multiple languages. Some on top of my head are: Indonesian, English, Chinese, Spanish, Vietnamese... That said, Chinese rarely give exclusive licenses, which means, tomorrow Webcomics or Qidian and hell maybe you could out of your own good will pay for the license rights, for the translations and lastly publish it on Mangadex for free so that everybody can enjoy it on free website with no ads, and then maybe, if somebody kindly donates, you can forward that to the author.
That said, I've said all there is to say on this subject in the comments below, please don't tag me about it again. If you have problems supporting mangatoon or official releases in general, that's something that you have to deal with, or maybe contact that jack person, maybe he can help.
