I don't think philosophy has been killed in stem, it is just that they are fed bits and pieces of it, without context of the whole, and in an incredibly purposeful way meant to counter revolutionary dialectical materialism.
For example, the engineering business philosophies driving global industry such as Deming or Shewart are ways of attempting to create a communistic ownership mindset within a company without actually giving ownership of production to the workers in order to have a better control over variability in production.
Deming straight up identifies poor management as being the primary cause of poor quality in products, and blamed basically all the things that we know are caused by capitalism without actually naming the beast itself. It is statistically driven Marxism without economic or class analysis, and in direct contrast to libertarian religious theory of what drives innovation. Of course, because of this, Deming is unable to come to a definitive reasoning as to why quality doesn't ever arise spontaneously in American corporations, but it is all there, it just needs to be put together with a spirit of revolution. But that doesn't usually happen because engineers in this country are still fairly well paid, move up quickly into management positions, and are also on the whole denser than tungsten when it comes to putting philosophical ideas together into a coherent whole.
