If Bitcoin is not at fault, why are the Bitcoin developers working hard to fix the issue now... Yeah...

Because the value of their assets dropped 50% and will continue to drop unless the problem is fixed.
And they worry that mtgox is too incompetent to fix it themselves
The price has already stabilized, so far as I can tell.
Enough people have heard and believe that a fix is imminent to help stabilize the price.
If too long passes without said fix materializing then more and more people will believe it to be a scam and bail out
