That's because back then the odds were so unbelievably shitty that the only reason you would play survivor is because it was fun to survive against the odds, typically while surviving you had some bravado with your fellow survivors, you all knew you were fucked and were going to be dead in 5 minutes and there was no point pretending it was any other way so nobody tried to be a hero and everyone just accepted it.
Then survivor became actually playable outside of just hiding in a locker and accepting your fate wasn't on the table any more because you actually had the means to fight back and didn't just have to hide in a corner and pray you were in an obscure enough position to not be found too early. I'm guessing from there it became more attractive as a combat role and less and less as an RP role.
I remember walling yourself in the LZ1 Solaris cave that used to connect the marshals perma-brig to LZ1, and just holding out there until boilers came to melt the walls and kick your ass. LV for the secure dome, everyone taking turns welding the walls down and repairing them back up so the eye damage wouldn't be too severe because getting welding goggles was off the table. Stuff like that never happens any more.
