EBITDA should really be renamed EBMS: Earnings Before Manipulative Shenanigans. A high net profit might be heavily correlated with high EBITDA, but it's relatively easy to show a GAAP profit while being in terrible financial shape, and not so easy to do that with EBITDA.

In this case, I'd consider Dropbox's emergence into slight EBITDA profits as not great, but a definitely welcome sigh of relief for a unicorn market full of bullshit.
