When you finish a PhD in computer science, they take you to a special room and explain that you must never use recursion in real life. Its only purpose is to make programming hard for undergrads.

It's easy to reject papers. You can manufacture issues and sink them based on amorphous/vague notions such as novelty, impact, clarity, etc. Every paper has minor problems that you can amplify. It takes a lot more courage to argue to accept something.
