Materialism isn't just "where everything is matter or energy". That's reductionist. Idealists can agree that things are composed of matter or energy, the same as materialists. The idea of a conscious mind isn't inherently idealist either, as things which are intangible can still be material. Marxists do not deny the existence of a consciousness, instead they acknowledge its existence. The difference between materialism and idealism is how our consciousness interacts with the world. Materialists argue that it is not consciousness that dictates reality, but reality that dictates consciousness. In other words, there can exist things which are independent of our consciousness. Idealists argue the former, stating that consciousness dictates reality. It's the reason why gods or angels exist within the idealist mind. Idealists believe in the existence of an angel, although it is a product of our minds, and does not exist within reality. Also combining "ideas" with "idealism" supposes that Marxism is also idealist. Science is idealist. Ideas are not inherently idealist, the concept of idea is the formation of our mind, but these ideas can also have some application with reality. Marxism is a set of ideas, it is based on science, which Marxists observe the political economy and form ideas which align with reality.

Your first paragraph doesn't align with the 2nd to last paragraph. If Marxism is simply a different view, why must we have different views? What makes Marxism different from a cyberneticist? I read your examples and they show vastly different things. And your 2nd to last paragraph shows that clearly. Marxism is different from an economist, a cyberneticist, because it looks at things in a different view within the application of the political economy, something which an economist or cyberneticist cannot do. Also saying "the contradictions are sharpening" is vague. What contradictions? What application of Marxism are we using here? We are referring to change, but there are several types of change, with negations or quantitative to qualitative transformations. All of this seems to be speaking in absolutism, in isolation from what Marxism is supposed to be.

Also saying this:

Ultimately the entire thing is fancy language from the 1800s that should probably be replaced because it’s alienating and bad for propaganda.

Why? Why is it bad for propaganda? We used these terms for centuries now and now we need to change them? The proposed terms are absolutely vague. "Conflict" does not speak of non-antagonistic contradictions (i.e. Proletariat-Peasantry), "tradeoff" does not speak of what dialectics truly is (It's not always binary, in fact suggesting dialectics is inherently a binary thing is metaphysical). "change" is absolutely vague because of what I said earlier. The term "motion" is always referring to change, a specific type of change. Ultimately dumbing down terminology should be done for beginners, but not for the sake of sacrificing the word itself.
