If it goes in the direction it feels things will, then SIE's approach will be virtually indistinguishable from Microsoft's.
Also, I just re-read the position listing, and what you're specifically saying isn't mentioned anywhere in there. I think you're simply choosing to interpret it that way but the language described throughout the job listing suggests games in general, not just live service titles. Otherwise, it would have explicitly mentioned live-service titles because, y'know, that's not too difficult to do?
