I had no idea that Dropbox had topped $1B in annualized revenue. Their new profitability gives me some measure of confidence that not all of the Unicorns are facing inevitable doom.
"Profitability" can mean whatever you want it to mean at a given moment. In this particular case it's closer than a lot of measures, but it's still a non-GAAP profit. In general these sort of startup announcements are marketing materials.
Every company I've been at has declared themselves "profitable" -- the devil is in the details of what you choose to ignore.
