On one hand, yeah, may be nuanced message doesn't work at scale. However, when saying literally two things (vs one) became nuanced. I wound understand if it was a speech talking about a dozen of different things and their interplay... These were literally two things - create a solid product and let's move forward fast. That's it.
Also, why the hell whole hierarchy of middle management exist in such case? The only reason for it to exist is exactly ability to execute at scale (when things which are coming from the top are propagated properly).
When in fact these things, and 100 other goals and considerations like being green or hiring fairly or paying interns better etc... merely influence each other a little and don't preclude each other except at absurd hyperbolic extremes.
The different goals DO influence each other. But the output product can in fact have a whole bunch of both speed and reliability, probably at the expense of yet another dimension like cost, but actually the same applies there too, you can possibly have all 3, at least to some degree, if the leadership is insightful enough to figure out a way like employing underutilized people or geography, or gamification or crowdsourcing or alternative incentives, whatever.
Pay more or sacrifice in one dimension to get more in another is merely the obvious and easy way, not the only way dictated by some zero sum law of conservation.
