Can anti-Bitcoin trolls use that to take advantage and spam the network? Yes they could, but it will come with a cost of paying higher fees. The bad-actors will waste their Bitcoins merely to cause a temporary inconvenience. From Bitcoin's viewpoint, where did it fail? Because it didn't. It's still chugging along producing block after block, incentiving miners for providing security the network.
Almost 2 months is more than temporary inconvenience[1].

Plus the Core Developers would probably be in a better position to do something if they study the issue more slowly/carefully. Bitcoin is currently valued at almost $1,000,000,000,000. That's ALMOST ONE TRILLION. The developers SHOULD be more careful and they shouldn't do anything too hastily. Because if the network breaks, there goes the evolution of money.
