After reading through this I am convinced that the author learned nothing novel outside of fundamental operations methods I regularly see deployed at companies of all shapes and sizes.
A lot of people in tech haven't collaborated with experienced product managers either, or owned little of the financial/growth side of launching something, where these kinds of questions get ingrained into you pretty fast. Much more of a dark art imo is how to act on them without giving your team whiplash and crushing stress (beyond their comment of 'keep innovation teams small', which means fewer people will still suffer the same problem)
