That's an entirely different position. I concur that Sony are happy PS4 sold so well last generation that they could leverage the ability to get some titles on that older hardware.. There is clearly a line between what does get a PS4 port and what does not. Miles Morales and Horizon Forbidden West weren't originally announced for PS4 but those announcements came later, some with a little surprise - although being originally PS4 titles it makes sense. The same for God of War Ragnorak. Titles like Demon Souls, Ratchet & Clank, Returnal and The Last of US Part I did not come to PS4. It feels like Sony have gone to teams can asked if titles can work on PS4, and released those they can, and skipped those that were viable.
This doesn't change that Sony would have much rather sold more PS5 consoles and been able to drop PS4 support earlier because that would have been more profitable in the round.
