Is this off-topic?
For what it's worth, I voted in the review queue to leave this open. This was primarily because of comments from @user4894 that I think could be converted into an interesting and unexpected (to me) answer to the question.
Perhaps what might help is a reference to one of the Marxists who "talk about the internet". This would focus the question and make it about that Marxist's views as much as about the topic of using the internet for class struggle in general.
