Yes, he over simplified.  What he should have said is that by the same logic Satoshi was "responsible" for the BTC pump from <$0.001 to >$1200 and should have been "responsible" when it subsequently crashed to less than 7% of that amount. Satoshi should have been responsible for the price of BTC after SilkRoad seizures, and Chinese and Russian 'bannings', and of course Mt. Gox.  

It's funny that no one ever seems to scream "the dev should stop this madness" when a coin starts being manipulated into a parabolic rise to unsustainable levels (usually on nothing more than hype and shilling)... after all, that's a free, unregulated market.  On the other hand if a coin loses value at all, or even gains but gains nearly nothing... it's the devs' fault that everyone lost/didn't make enough money.

It seems to me that I remember the earliest buys I made in BC being for around 2000 sats (hours after it got listed)... so despite it being dumped to less than 500 a few weeks later... let's call that the 'initial market value' of a BlackCoin.  The current price represents a little over a 300% gain on those prices.  Seems like rat4 did his job then.

Now if you are someone that purchased initially during the irrational and artificial pump to ~97K, or if you bought more of your holdings at that level than at the earliest ones... then it's certainly not a gain and perhaps is a huge loss for you.  But unless you can show me where rat4 (or any other dev for that matter) held a gun to your head and made you push BUY on the exchange... there's only one person to blame. If you don't have a mirror, I would suggest getting one so you can yell at the responsible party face to face.
