I count 8.89% of all nodes now... where are you getting your data?

Bitcoin Classic math: Computing a proportion as x/y instead of x/(x+y). But hey, they're totally ready to handle making critical survival decisions for a global decentralized cryptography consensus system.
Miners have direct control. Nodes /users, merchants, processors/banks/exchanges can and do influence miners by buying or selling their product, the coins. They may even form an altcoin if miners go against them in a way that is intolerable.
This is simply untrue. Lets imagine that 75% of miners start paying themselves 50 BTC again instead of 25 BTC per block. Nothing, it's the same as if they simply turned off (which they may do when the subsidy halves). Nodes simply ignore their blocks. So much for "direct control". Miners do have power over some things-- they can choose the order of unconfirmed and recently confirmed transactions; but they can't break the rules of the system enforced by the nodes... if they do, they're not miners anymore as far as the nodes are concerned.
