Blame philosophy as a field for actively kicking out anything which gains a practical application. If it is propaganda it is coming from inside the house of philosophy.

I had a computer science professor who had degrees in philosophy because he was old enough that computer science didn't exist as a major at the time. The logical arguments of philosophy proved useful for understanding interactions of boolean mathematics. Yet that triumph of philosophy didn't further interest in the field or gain prestiege among philosophers. Just the opposite really.

As far as I can tell it is for dumb reasons possibly related to Ancient Greeks and their obsession with 'purity of thought (read: not referencing reality) it is practically an axiom that if it is useful or grounded in objective reality it isn't treated as philosophy anymore. All likely stemming from motivated reasoning against checking their priors and from frankly many of the Ancient philosophers being influenced by a need to flatter their patrons who held the practical in disdain. As notoriously seen in Aristotlian physics with impetus physics where projectiles keep moving in the same direction until impetus is depleted and then fall.

Speculation of the origon of the pathology aside, there seems to be this deep-seated antiempericalism in philosophy. Which means at best you get 'philosophy of science' which isn't proper philosophy because it pollutes itself by daring to use reality and experimentation as benchmarks for theories. When philosophy gains a practical usage it doesn't become something called 'practical philosophy' and the focus of more interest by philosophers, it gets shunned. Natural philosophy didn't remain philosophy - it became science.

To be fair there is probably some interaction driving the divorce from the opposite direction, of the practical portions of philosophy being pilfered by those only looking for results as opposed to some sort of unquantifiable enlightenment.

Science is of course a process of refinement of ideas against the reference point of reality. Anything mathematically consistent can be a model but experimentation is needed to see how well your model corresponds to reality.
