Marxist Irony, iTunes Edition

On my iPhone, I have five apps that I use quite regularly (two more than the other three). They were free, and are e-readers with the texts of:

Thomas Paine's Common Sense
The Declaration of Independence
The Federalist Papers
The Constitution of the United States
Adam Smith's An Inquiry into the Nature and Causes of the Wealth of Nations


All free! Even the capitalist bible of The Wealth of Nations!!!!

So, it occurs to me that it might be nice to be able to have the opposition's text(s) too, so I just searched on the iTunes AppStore for The Communist Manifesto (Marx/Engels) and Das Kapital (Marx). Care to guess what I found?

Yep. There are no free apps with the texts of those two. Funny that someone wants to make money off of Marxism, considering that the works - all that I've listed - are in the public domain.
