@KenOne That's not exactly an accurate description of the business model on Webtoons. The chapters are free to begin with, fast passes do allow you to read them very slightly earlier than free users but free chapters are still a weekly or even multiple times a week thing anyway, and then eventually once the series is completed they'll decide it's time to monetize it all over again. Leaving the first maybe 3-14 chapters free, and removing everything else from their website so, it's only on their app where you can read one or two chapters freely on a daily basis but would have to pay to read more than that at a time. With a longer series, imagine trying to deal with hundreds of cliffhangers one chapter at a time.
It's a pretty obvious tactic to incentivize just buying access to them all outright, but their system for that is exactly like a cash shop in an online video game: the pricing is set up to specifically be a pain in the ass where you buy virtual money in a quantity that probably exceeds your needs, and the leftovers won't cover a goddamn thing on their own. It's arguably overpriced compared to buying a physical copy of a series of that length too, with the numbers I figured out for one of their series, but not everything on there has that option. I think the ones I did see like that were actually western authors self-publishing their work, rather than the things Naver/Webtoon had all along from Korea doing so. I'm pretty sure they have published Korean physical copies, but I'm not aware of them doing that for anything translated. If I'm wrong about this part, someone should feel free to correct me on it.
TL;DR version: Webtoon's monetization system is pointlessly convoluted and designed in a way that would make the money grubbing whores in the video game industry proud.
