Why is there a pickup insurgent on ps3

Question

So, it's been going around that GTA V online on the PS3 will no longer receive updates. I'm starting to question that because there's a Humane Labs heist with Lester that unlocks the pickup insurgent after the finale.

I thought the pickup insurgent was a part of the gunrunning update for PS4, Xbox One, and PC. Was that update also on the PS3?

Answer 1

The reason you can get it is because the Humane Labs Heist is part of the "Heists Update" from back in March 2015. This also included the Insurgent as an acquirable vehicle.

Gunrunning is not at all apart of that Heist, nor the vehicle.
