why don't people subvert borgs/ai as much anymore

[ZeWaka]

also literally all you need to stun and fuck up a borg is a flash which can be found in various places all over and manufactured in huge quantities from hacked robotics fabs, borgs lack ranged weapons and insta stuns and cant wear sunglasses a flash is your key to reducing them to childsplay

Wrong. You can completely negate all stuns on a borg with a module.

also ais can be blinded by snipping their cameras rendering them impotent in large swathes of the station

Make AI Interface cards for a borg. Or use AI shells to murder people, highly effective.

theyd rather suck out all the air first despite the fact that humans can put on air tanks and space suits

Yup, tons of traitor borgs are dumb and actively make humans get more equipped for airloss. A better tactic is flooding the station with co2 in some areas, removing oxygen in some, n2o'ing some, and setting fires in the rest.
