Well, it's been in development for at least 7 years, without any product until the url parser appeared. That's far greater of an investment with no return than I've seen at any software enterprise outside of Google X, Microsoft Research, and Intel's various funding efforts, and each of those arguably have had more projects cut off before they return than they have had projects that succeeded in generating some return.
Enterprises tend to invest in <5 year projects, I've noted, and 5 years is a hell of a long time for an extended investment.
