Earlier quoted context omitted.
Some of it is that "legacy" products often involve more difficult engineering than people think. Circa 1980 this bus design was a notorious failure in NYC: https://cptdb.ca/wiki/index.php/Grumman_Flxible_870 Buses get shaken really hard.
It is amusing/depressing to consider this as getting punished for having expensive engineering to avoid failures. If you do put in more engineering to get a more robust solution, you wind up not hitting the expensive failures and people start to assume you just spent more money in engineering than you needed to.
Nowadays with spending power way down, it may in fact be more "efficient" to get something out quick, and have frequent repairs. If you hit the expensive failure... welp, just throw it out and make a new one.
