For example: Compare Hatcher’s proof that homotopy equivalent maps induce equivalent homomorphisms of homology groups to Massey’s.
Cubical homology though. Just…why.
Seconded on Cubical homology; but of course you all know that the preferred construction of homology is as homotopy of

First, he considers what individuals do with informational privacy. What is an interest in privacy of information, he asks? Well, it’s an interest in enforcing an information asymmetry in markets....
