You might as well say not enough credit goes to Tommy Flowers, a man I have always admired for his ground-breaking work building Colossus.

Well that is the class system, Tommy was working-class whereas Alan Turing was a posh boy who went to boarding school and Cambridge. So of course he was airbrushed out.
