The fancy new hotness gets pushed onto them by smooth-talking evangelists.

Gets pushed onto them top-down. This means there is no real competition, no real empiricism, no real comparative merit involved in the switch.

How should never be imposed top-down. It's only goals and how success is measured which should be top-down. The classic example of this was when Jeff Bezos mandated that all Amazon software systems should be accessible by APIs over the internal network, or else one would be fired.

Whenever I've seen How imposed top down, I've only seen the lower level managers talk about how they could put off and passive aggressively stymie the initiative.
