To be fair, the anime-styled comics show up more in Popular and similar places because they're, well, what get popular, most of Webtoons' audience are teenage girls (like... me) and would gravitate towards comics with that kind of style cuz that's what they're used to. Lots of them are weebs, people. A lot of them really like reading manga.
Still sucks though, but I can't entirely blame Webtoons for that. They're a company that needs to make money, so the algorithm kinda picks up on those anime-styled comics because a lot of people are reading them.
