It's interesting how the meaning of the word 'propaganda' subtly shifted from value-neutral 'publicity, promotion advertising, media' to specifically 'deliberate official falsehood' over the 20th century.

A lot of other words used by 20th century Marxists have similarly changed meaning or emotional valence.

It would be sensible to avoid using many of these technical jargon words if you don't want to summon the new meaning rather than the original one.

I'm looking at you, 'proletariat'.
