At first appearance one would assume it's a duopoly because they designed it to look that way. In reality it's a uniparty similar to wings of the same bird. The duopoly is just the illusion.

Take the "uniparty" and now split that again and you get the people that understand the uniparty, how they work within as a virus and they to have a grassroots movement to stop the uniparty.

It's a lot more dynamic than most understand and unfortunately I've never found a qualified meme that can grasp the concept and do a valid job of presenting it.
