I suspect the author of this knows more about programming languages than religions. But it’s still kinda funny.
C# would be Mormonism – At first glance, it’s the same as Java, but at a closer look you realize that it’s controlled by a single corporation (which many Java followers believe to be evil), and that many theological concepts are quite different. You suspect that it’d probably be nice, if only all the followers of Java wouldn’t discriminate so much against you for following it.
