Yes and no. It does, but it works a little differently. Most WEBTOON Originals remain free to read while releasing, whereas only some of those on Tapas do; others go behind paywalls, or a daily pass system. It's up to Tapas and the creator to decide how the comic will be released and monetised.
The licensing and IP rights work differently as well, as you give over 50% of your IP rights. (This is so Tapas can pursue potential TV deals and so-on on your behalf, but functionally, it means you're not in control of your IP anymore.) This isn't an issue for many creators, especially those with shorter, self-contained stories, but it may well a dealbreaker be if you have a long-running series which is very dear to your heart.
