To be fair, the Doctor asked what Voyager's crew compliment was, not who was on the ship.
To be fed, I'm assuming that replicator rationing had not been suspended, and even so. do replicators just give food to anyone? To keep the ship running, the computer would have to be deceived into believing that it's current crew was lawful and even diligent. The 89 Kazon had been staffed to Voyager to fit into specific positions and roles and therefore seen as crew, and allowed to eat, even if they were not doing their job or were only allowed on board through a guest pass. They needed to justify their existence to the computer as someone worth looking after, which it seems they didn't do so well, since the computer didn't care one way or the other who it was helping take the ship. The Doctor or the Kazon. The computer did not care.
Seska is not crew, she is a passing through dignitary, like any of those assholes that used to swing their dick around on Kirk's Enterprise on a fastpass to cocking up.
I find it off that Suder is still thought of as crew and not as an escaped prisoner who the computer should be sending Security after, who are now ironically Kazon thugs disgusted by Starfleet.
"Sigh"
