Agreed but, Electronic computers, the Jet engine, Radar, the Cavity Magnatron all Britsh inventions. The diffrence was we won, so could keep our secrets. A lot such as Enigma were kept secrt for both political reasons, there was a desire post WW2 that the the cult of Germany not be defeated by military means but political cowardice that prevailed following the 'I fooled the Hun' tub thumping by various Brtitsh personalitys after the Great War, and used extensivley by Hitler would not be repeated. There was an immdiate concern over Stalin's intentions, and such assets were deployed aginst the USSR. Then there was the reparations to the US, which means a lot of British invntions are claimed by US firms. None of this required slave labour or coercion. It was also nessacary that Germany be allowed dignity, as the country was now the Front Line in the Cold War.
