I haven’t watched the video, but two things I wonder:

• Surely he signed an agreement when he was hired promising they could hit him with an enormous lawsuit if he ever spilled “muh trade secrits.” I’m wondering how he got away with this unless all he’s sharing is public info.
• Is anything Atlassian has done really that non-obvious that anyone couldn’t just reproduce (or improve on) it from scratch just given some thinking and elbow grease? (Like, Confluence is a glorified WYSIWIG editor. Bamboo is Jenkins slightly spiffed up so it doesn’t still feel like something straight out of 1991. And another Jira can be easily procured by anyone willing to travel to hell and request the next steaming shit Satan takes.)
