Decribing itself as "the one and only alcohol industry watchdog", Marin Institute is an organization dedicated to highlighting the harms of alcohol. Last week, it rebranded as "Alcohol Justice". The old name was considered "respected but not informative", as its activities aren't limited to Marin, California, and it isn't an "institute" that does research.
The press releases provide no further information on the logo, but it clearly includes a person in the middle, made up of the letters O and T.
