I think the idea is more that if this were in place companies like Sony would be more incentivized to make sure they release games worth buying and playing, because if they didn’t then they would have the financial burden of keeping them alive.

Side note: it doesn’t require constant support from the developers. Just update it so players can run local servers, then it would technically still be playable. Of course I’m not a game dev so I’m sure thats more complicated than I’m making it sound, so that’s again why they should focus on making games that are good to begin with.
