Have you ever thought it was Sony at fault, not Treyarch?
Exactly the same way as COD4 on xbox and join session, and Ps3 didn't, and that was infinity ward.
The second part of what he is asking CAN indeed be done on the PS3. The only thing you can't do is join a person's session unless you're friends. Which would be a nice feature but only people who really want to do that are those looking to join really lower level players to get easier noobs to kill.
Wouldn't blame Sony or Treyarch in that particular regard. Especially since MW3(infinity ward I know but still) they removed they disabled the ability to join a friend's session without an invite. That wasn't a Sony issue since BO1 and now BO2 allow it. Maybe the OP's first question COULD have been implemented. It's probably not a big enough deal to make a thread about a potentially start any stupid console war conversation that is sure to follow...
