Replit, a company that offers a web-based code editor, threatened to sue the author of an open-source project called Riju, which allowed users to run code online in multiple programming languages. The author, a former Replit intern, had shared the project with Replit, but they accused him of stealing their design and making a clone of their product. The author took down the project, but later wrote a blog post about the incident, which led to a public apology from Replit's CEO. The project has since been put back up.
