PR campaigns to try to "convince people with ideas" to change their ways is definitely more on the idealistic side.
Tech that fundamentally changes the means of production of a fundamental commodity in local, regional, national, and international markets seems more on the materialist side.
I agree that those would be good, commonsense ways of using those words. It's also not what Marx meant by them. So when you throw them around on a Marxist forum, it gives a weight to what you're saying, but without actually referencing anything Marx said.
From what I see:

Do you see how this could create issues?
