It's funny how times change. My first thought was "that's a conflict of interest and it would've been polite to mention it." He apparently doesn't believe that his collaborators might have their own ways of dealing with conflicts. But then: I think it's a generational thing. He is from a world where people have simple allegiances and hidden conflicts are rare. In the Internet age relationships are so fragmented conflicts of interest are part of the day to day collaboration process.
