1. I don't really get what posting this as an image gets. I would understand if the image was related or incorporated with the message but this is just some vague space motif.

And the lords opportunities to enrich himself with the sold pitchforks were very limited compared to computers. However while the analogy is a bit scruffy it is ultimately valid. We are limited by the tools of the current regime, even if we want to overthrow it, as not using them would make us invisible.
