Twitter to Ban Political Advertisements Facebook has been under scrutiny in recent weeks due to their handling of political advertising. Twitter Chief Executive Jack Dorsey has decided to take the opposite stance of his social network rival regarding the issue. Dorsey announced the move in a series of tweets on Wednesday. However, Dorsey did say that there would be exceptions, such as ads promoting voter registration. Though many seem to support Dorsey's stance, Twitter shares dipped slightly after the announcement.
