I think most people involved in BTC (the community) do realize this is an attack. I, for one, do.
A siege, though, is not a generic attack. It involves being starved by the enemy outside, which can't happen as long as we keep our provisions (BTC) - that is, if we don't trade BTC for BCH.

I am convinced that the value of BCH will vanish soon, unless it is artificially (and expensively) pumped from the BCH side. Which they are welcome to do, as far as I'm concerned. I'm going to trade my BCH back into BTC if I see steady rates in the order of 0.3-0.5 BCH/BTC.
