GitHub - SerenityOS/serenity: The Serenity Operating System 🐞

I don't know about the creators of this project, but in general: So that they can use the stuff in their closed source applications while finding enough contributors to write software for them for free.

For some software, where EEE tactics aren't a concern, but corporate adoption matters, these licenses make perfect sense. However. that's not the case here: an OS is a prime target for EEE.

What is your issue with the licensing?
