Turing was persecuted, but he was also instrumental to the Allies' victory in WWII. Without Bletchley Park and the massive advances in electromechanical computing that Turing helped to spearhead, the world would probably look very different today.
It seems more like an acknowledgement that his past persecution shouldn't have any bearing on our perception of his myriad accomplishments. FTA:
>Alan Turing provided the theoretical underpinnings for the modern computer. While best known for his work devising code-breaking machines during WWII, Turing played a pivotal role in the development of early computers first at the National Physical Laboratory and later at the University of Manchester. He set the foundations for work on artificial intelligence by considering the question of whether machines could think.
I mean, we sometimes call general-purpose computers "Turing Machines", and we use "Turing Tests" to determine if an AI can demonstrate enough intelligence to pass as human.
