In this sponsor podcast you'll hear an excerpt from Crispin Cowan's talk. Crispin works for Microsoft, but he used to be a vocal Microsoft critic and Linux fundamentalist.
These days he spends his time trying to retrofit Windows with decent security. He works for the Windows core team.
I'll drop you into the talk here where he's explaining how certain bad things happened to Windows and the Microsoft ecosystem, namely, how interoperability concerns hampered the software company's ability to secure Windows.
