There few earlier developers, who think they are all 'Satoshi'. Its mean they want to not only infringe Satoshi's intellectual but his very individual persona. That could become a hideous takeover, which is not ethical. The outcome could be soothing like much more undesirable.
The "we are all Satoshi" movement is obviously not to be taken literally. That movement just came up after the barrage of people claiming to be the "real" Satoshi, to sort of symbolize that Satoshi is anonymous and could be anyone, but not those who claim to be so because it obviously goes against the ethos.
