It is not "Krafton free". Unknown Worlds is completely owned by Krafton, Krafton isn't just "the publisher". There was a complicated lawsuit that led to internal reorganization, and some napkin math that suggests there's some number of lifetime sales that, if they don't ever sell more than that number or significantly less than that number, the project will lose Krafton money because they'd be legally required to pay out the "bonus" that the drama was about in the first place (but not make enough profit to actually afford paying that bonus without dipping into profit from other games). But it's still a Krafton game developed by Krafton employees.
