I joined them after they were clearly in decline and half of the office was empty. Contrary to some of the comments here, there were enterprise products (Docker EE, private registry, orchestration) and a very large sales team.

There were also a lot of talented, well-paid engineers working on open source side projects with no business value. It just wasn't a very well-run company. You can't take on half a billion dollars in VC just to sell small enterprise support contracts.
