That makes sense, but i think there's bleed over to libs using it as "capitalism was great, but now its tech feudalism." The same way they used corporatism and crony capitalism to act like its a deviation from their platonic ideal of capitalism that they're sure totally existed once but not now

I find it's useful for getting people to seriously think about how, for instance, health care is used to enserf people, tie them to a company they cannot leave regardless of their treatment. People often think of themselves as free, as choosing their employment and their "career". Serfs, though, don't choose. Getting people to think in those terms can be useful.
