However, consider this: Based on FS1 monologues, what kind of factions do the Shivans go after?
Multiple readings are possible. For example, meditate upon this line:
We know when we entered subspace we were trespassers.
The Ancients monologue speaks of a specific crime, a specific sin. "Now we know our crime was sin."
It speaks of such sins after
their imperialist expansionist tendancies, so it is at best an extremely tortured construction that they were referring to such things. Instead, the closest that would come to an identification of sin is the trepassing.
Subspace is also mentioned in more than one of the monologues, three of them in fact, but imperialism only one.
And also, this one:
In the Vasudan war, we learned how to adapt, we learned how to study our enemy, we learned how to overcome, we learned how to survive. And so we did.
Alpha 1 lays it out. Humanity survived, the Vasudans survived, because they were strong, because they were prepared and capable of fighting for it.
And both these ignore the vital point: It doesn't matter whether you're imperialist or not. It matters only that you be curious. The Shivans do not arrive from extradimensional unreachable homes to destroy those who break their rules. They did not for the Ancients and they did not for FS2. They are here
, now, and they await the unwary as they awaited Bosch's effort to find them. Even harmless exploration could bring down the wrath of the Shivans upon you. Unless you're posisting that Ubuntu is so insular it will never even explore beyond known space, some day they will meet the Shivans once more. And they will not be ready for it, they will not be able to buy they few days necessary to throw a pile of Meson bombs down the node and render themselves safe again.
