This seems pretty misleading. The WHO put these meats in the same class in terms of certainty of being a carcinogen in humans, but I don't see any claim about the rates of cancer caused by each being comparable. That is, they're convinced that it causes some nonzero amount of cancer, but how many cancers it causes is a separate issue.

Also, the picture at the top shows a cheeseburger, but ground beef is never actually mentioned in the article as an example of "processed meats". It represents an older consensus (seemingly unrelated to the current topic apart from the shared theme of "meat bad") that excessive red meat intake contributes to health problems.
