WTF?!!
Did you read what I just posted? This is NOT a business!! @Ibeatdungeon, Ask the dev or OP why it was closed, they don't have to give an answer. This is a contributed project. It's not even in the guidelines for devs to say why they closed an issue.
Now... with that said.. yes I agree: some explanation would be nice, however, it's entirely up to the devs to adapt a "polite" mannerism to issues while closing and/or commenting.
