this is not the first time someone tried to take over bitcoin. it is just a new way of doing it. in the past there has been numerous attacks against bitcoin and there will be a lot more and as bitcoin grows the number of take over attempts will only increase.
The question of what form future fuckery will take intrigues me.
At some point, hopefully soon, the idea of doing it via another coin will be laughable and indeed it's very disappointing people are dim enough to follow it now.
There'll come a point where attempting the same thing will be like a flea trying to rugby tackle an elephant. It'll simply be ignored completely.
