And the thread from yesterday (https://news.ycombinator.com/item?id=25590846 for a site named https://whyjirasucks.com) or any of the other many rants on Altassian around the web don't suffice? I hardly think that this thread is going to be the tipping point. It's not like this is news.
Given your opinions regarding Atlassian, what would you think of your next CTO if they were even considering Atlassian? Is that someone you'd want to work for?
