Well, so far Osborn has "worked" while in charge by giving people what they want. Doom gets Latveria, Namor gets missing Atlanteans, the Hood and Co. get an air of legitimacy, and Emma and Loki get... get...
Well, I'm sure Emma and Loki get something, but I'm not sure what.
That's a few people Osborn can deal with in a more subtle and appreciative way than Nick Fury or Tony Stark ever could. This could be Norman's willingness to work in a way Nick and Tony never would. But you don't have to be evil to be a good negotiator. Dale Carnagie proved that.
