Ackman was a prominent critic of former Harvard President Claudine Gay, who recently resigned following charges that her academic writing contained examples of improperly credited work. On Sunday, Jan. 14, 2024, Business Insider’s top executive and parent company said they were satisfied with the fairness and accuracy of stories that made plagiarism accusations against Ackman’s wife, a former MIT professor.
