"Yahoo has quietly left the U.S. Chamber of Commerce, MT has learned. For Yahoo’s part, a spokeswoman would only say to MT that the company “has memberships with numerous trade associations and belongs to a number of organizations that promote a free and fair marketplace which enable Yahoo! to innovate on behalf of our more than 700 million users. As our membership renewal time neared and we reviewed our membership, we decided not to renew."
Yahoo didn’t elaborate any further, and the Chamber said it does not comment on membership changes. But we know one thing for sure: The two didn’t see eye to eye on at least one issue. That’s the PROTECT IP Act, which the Chamber strongly supports and Yahoo greatly opposes. We’re following."
