This is very true and I think it is often understated, the influence that we developers have over the spread of a certain trend or technology through the mechanism you described. Now imagine if you're a company that have 50k or 100k developers on payroll. Even that alone will actually spread your influence if you indoctrinate them right, might be worth hiring them just to double down on that influence, even if you may not necessarily need them.
