First off, I'm not "White Knighting" Eureka. It has its issues and I readily accept those and believe they need to be addressed. You find it horribly offensive to your sensibilities, fine, but there are some good points amidst the bad ones.
Second off, I didn't tell him to "keep it to himself". I told him that if he wanted to discuss his issues with Eureka without inflaming masses that he should have kept it to that topic and not espoused over the fact the he's unsubbing over it. The content failed you, fine. Complain about the content, talk about what you don't like, how and why you want it fixed or why it's not for you. He stated that he didn't want this to be an angry discussion, but when you start a conversation the way that they did you're going to get people up in arms, plain and simple. If he wants to leave that's fine, but he doesn't need to get on a chair and tell everyone that he's leaving. If you did this in public at, say, a bank and said, "I'm closing all my accounts here and let me tell you why!", people would not respond well. If you, instead, stood up and just said what problems you had, people are more likely to listen without getting pissed off.
So I'll thank you not to put words in my mouth and take my comment horribly out of context. Good day.
