After consulting with an unnamed "someone with legal experience" (Sharpie would only say "they claimed three years of law school"), the Suyu development team has decided to avoid "any monetization," Sharpie said. The project's GitLab page clearly states that "we do not intend to make money or profit from this project," an important declaration after Nintendo cited Yuzu's profitability a few times in its recent lawsuit.

From the article, they explicitly state they're not trying to profit.

Worth noting, this isnt Jagex nor just a random former employee. The Gowers made the OG classic game. I'm tentatively excited for this one. High hopes, low expectations
