I think that technologists are doing themselves a disservice by blaming the problems within their industry on MBAs. Many of the problems we see in the tech industry, and the reason why public opinion is not exactly positive, are primarily due to ideological factors. Whether you call it Californian ideology or whatever, many people in the tech industry think only in terms of efficiency and value. And if something isn’t efficient or doesn’t add value, it should be streamlined away and made obsolete, whether it be systems, processes, markets - or humans.

The MBAs exploited and greatly exacerbated the ideology factor by making ever increasing demands for monetary performance. In the beginning it's usually just about the tech, but soon it becomes how to make more and more money in any way possible with the tech because "the more money you have, the more tech you can buy or make".

Yep. You can try blaming it on MBAs, but the people that did this (e.g. Ellison, Andreessen, Musk, Zuck, and so on) are not MBAs.
