Who allows DFINITY employees to represent ICP officials?

The DFINITY foundation should and could be elected through NNS without any loss of organizational efficiency. In fact, this can completely solve the decentralization problem of any public blockchain with POS, as long as it has such a wonderful mechanism as NNS.
But it seems that everyone in this forum is so frightened by this idea. I don’t know why.
Maybe IC is indeed a private chain.
