I really don't 'get' this anti-infographic movement - What's the difference between text-based content and graphical content? Gaming sites like Digg etc is always going to happen regardless of the format.
1) Humans respond in intuitive, predictable ways to graphics, particularly with a greater emphasis on emotional response. (As opposed to an analytical response.)
2) All information sources have bias, and any marketing competence on the part of the infographic creator will tend to subconsciously amplify the bias of the graphic's creator.
3) Combining the creator's bias with the infographic's tendency to more easily invoke emotional responses over analytical ones results in a reaction more couched in that emotion than in logic.
IIRC, USA Today was criticized for this, decades ago.

[I think] The anger is generally on the part of the critical thinkers against those exploiting sheeple. You can think as critically as you like, but that doesn't mean you won't be drowned out by those who don't.
