More then one path to victory?

This post stems from the theory that Snape was forced to kill 
Dumbledore so that he could cement his place on the Dark side and 
continue spying for the Order/Dumbledore/Harry/whoever. 

Is it just me or does it seem like Snape's role as a spy was 
undermined throughout HBP? Even as early as OoTP we hear of other 
spies in the wizarding world...Hagrid is in charge of feeling out 
the giants, Bill Weasley keeps in touch with the Goblins, Arthur, 
Tonks, Mad-Eye, Kingsley provide information from within the 
Ministry. So really Snape has only ever been important when it comes 
getting inside the DEs and by the end of HBP Harry has another 
possible source of information from the inside...Draco. And I 
believe that Harry would be far more willing to deal with Draco then 
he ever would with Snape. 

Even Snape's knowledge of magic is undermined...Harry has access to 
the Half-Blood Prince's most inner working though the Potions 
textbook.
