I think you're giving the reporter too much credit :)

Also, Atlassian is a good deal bigger than GitHub (if measured by revenue, profit, people or valuation), which would seem to put them on the Dropbox side of the analogy

Which is an interesting thought because the common perception (from my chair) is exactly the opposite. A matter of skewed perception, etc, etc.

I think the Bitbucket piece is smaller than Github. But Atlassian also have a whole bunch of enterprise-oriented products, more in the same kind of market as Thoughtworks or one of the big enterprisey lots.
