Yeah, but those are outliers drowning in a sea of free development tools. The price that they can charge is effectively limited by how much it would cost some to replicate the subset of that tool that they actually use.
A business that is paying $X/year for $DEVSOFTWARE for their entire devteam pays that only while $X is less than the cost of paying for developing the subset of $DEVSOFTWARE that they use. That limits what Atlassian can charge.
Compare to selling a tool to accountants - it doesn't matter how much $ACCSOFTWARE costs, the accounting department will only shop around, they will never just write their own (outliers excepted, of course).
