Actually, if you read the article and linked letter, you will see that this list does not seem to come from any explicit support of SOPA. Instead, anyone on this list and not on the official judiciary list linked above comes from a letter[1] not stating support for SOPA but rather petitioning Congress to "enact carefully balanced rogue sites legislation this year."

From the linked article: "This list is derived from two sources: the official list (pdf) of SOPA supporters from the Judiciary Committee’s website, and a letter (pdf) addressed to Congress from the Global Intellectual Property Center, which is an affiliate of the US Chamber of Commerce."

I thought this deserved clarification.
