Churchill, Whittle and the sharing of jet technology

Was Churchill responsible for Britain giving away jet technology without licensing or payment?

Churchill is assigned little direct responsibility; wartime habits of trust and Whittle's limited commercial skills carry more weight in this explanation.

Churchill is not given a substantial direct role in the transfer described by the question. The answer argues that relationships fostered during the war encouraged excessive confidence in informal agreements with the Americans. Whittle is assessed as a strong engineer whose commercial skills were much weaker. The wider lesson concerns the difference between developing a technology and protecting its commercial interests. That explanation is offered without tracing a particular licensing transaction.
