Just thought i should mention something...
Yuni's IC references to 'hive alvus' and their damaged core AI is from her own IC perspective...
Even Yuni doesn't know how the internal workings of the other hives are intended to work, after she and the other Units were attached to their AI they were left alone.
She has drawn conclusions based on the AI she was implanted with, but that does not mean that her AI is the same as the original Alvus AI, or the same as any other drone AI for that matter.
The fact that she sees the 'degradation' of their AI as a fault that should be repaired is very much her AI talking... her human side accepts that she and the rest of Unit are aberrations compared to the majority of drones.
in various rogue drone exploration sites and missions, you can meet 'sentient' drones... a lot of drones also drop 'elite drone AI'.... through her investigations into various drone sites and items, she has simply reasoned that the drones have deviated from their original purpose and become aggressive as a result...
considering that the majority of them were (apparently) originally construction drones... it is true that this has happened... though the reason is still... well..
