It's amusing to see "but it wasn't enough I guess" in relation to a profitable $10 billion company with 3,000 employees. That's a pretty good outcome!

Well, it’s relevant: Atlassian launched a paid issue tracker in 2003 when the open-source Mantis was all the rage.

There is always room for a smooth paid service compared to the rough free one. Android and Linux vs twice-more-expensive Apple.

True! It's still a useful product, but the pressure to keep getting huge-r is always there I guess. I knew someone who worked there and they seemed pretty desperate for new initiatives (like the failed Paper). Most of their competitors have online storage as part of their product portfolio. I don't know of anything else major that Dropbox does...
