That seems like a ton noise with very little, if anything to show for it. It still seems like the IWW is a weird place to start a search for unionization, or a model to follow.
I don't know what "noise" means in this context, especially as interpreted though the lens of Wikipedia where you are certainly reading through editor biases.
You said the IWW has - as in the present day - "an extreme ideology". Where is your evidence?
