Doesn't sound like they wanna do anything to effect the game or stop it from being released, but it is interesting how they worded that they want to sit down and have a "talk" w/ the developers.
This is likely down to the fact that while players are technically sharing the game's universe, and could run into one another, No Man's Sky's 18 quintillion possible locations makes the chances of such an encounter (to wheel out an understatement) statistically improbable.
That makes the game's only likely online interaction the mapping and naming of said locations, something which Sony clearly deems single player-y enough an activity to waive the necessity of PS Plus (which is required to access the online multiplayer features of most other games on the console).
