Glad you learned something. Normally this is where I get told that the marxist version of the term is wrong or dumb even though it's closer to the original meaning than the modern definition.

I am sure the authors of Merriam Webster don't mean anything harmful. Dictionaries update their definitions based on how they see the term being used, and many modern people don't respect the original meaning of the term. In political circles we still use the original meaning. You can see why this causes confusion.
