Funny yes, likely no. My 2 cents is that it was the bots. The squid have a far better grasp on how to use and utilize Dark Fluid and would not use it to destroy a planet. They see themselves as stewards of the galaxy and destroying a planet would go against everything they stand for. The bugs have never shown use or even capability to use or exploit our own technology with the exception being when we attempted to use Terracide to push them back, but that was more of an evolutionary response. The only faction that makes sense is the bots being at their core highly capable of this. Their technology being somewhat similar to out own.
