Koszul self-duality of manifolds

We show that Koszul duality for operads in (Top,x)$(\mathrm{Top},\times)$ can be expressed via generalized Thom complexes. As an application, we prove the Koszul self-duality of the right module EM$E_M$ associated to a framed manifold M$M$. We discuss implications for factorization homology, embedding calculus, and confirm an old conjecture of Ching on the relation of Goodwillie calculus to manifold calculus.
