It's not the principles, it's the actions being discussed to follow through with those. You know the phrase "I'm taking my ball and going home"? What he wants to do is take someone else's ball, go home, and make sure that no one else is playing with a ball again after he leaves. He's wanting to destroy something the community finds useful, and not only that, wanting to prevent the community from building and using it on their own in the future if they wanted to continue without his involvement. That's the harmful action. It's fine if he says "I won't use reddit anymore". Perfectly fine. But shutting down the subreddit, deleting all of its content, and specifically reserving the name so the community can't continue in his absence is just... well, immature. There are better ways to handle it. This is a pure temper tantrum.
