Sure sure, 5 years wasted by Bluepoint and Bend Studio is nothing. Also ND many years involved in gaas project isn't connected with fact that 5 years into generation we got some lazy remake/remaster of lou1 on lou2 assets and 1 trailer.
All companies, not only Sony, also commonly cancel non-GaaS games, they've been doing since the 70s and is part of gamedev process. It's dumb and nonsensical to act as if it wouldn't be the case.
Bluepoint doesn't have -and never had- anyone in the job positions related to lead a game, like game director, creative director and so on. Their game design team has under half a dozen people and were only two people during the GoWR development. So they aren't and weren't leading any game, because as their boss and Sony said multiple times they are a support team.
They also don't have and never had anybody in any GaaS specific job role, so never have been doing any GaaS specific stuff. They are a support team mostly focused on art, so somebody who can support both GaaS and non-GaaS stuff because the part they are in charge when codeveloping is the same for GaaS and non-GaaS.
Regarding ND, before TLOU Online they worked on a single big game at the same time. TLOU Online didn't stop them to continue working on SP AAA games, the opposite: at the same time they were working on TLOU Online they also worked on TLOU2 and when shipped it moved to Intergalactic. Around early 2023 they also started to work in a second, unannounced AAA SP game. So they were working in 3 big games at the same time. Plus at the same time they were overviewing/supporting the remasters/remakes/ports and movie+tv show.
So no, during TLOU Online deelopment they didn't decrease their efforts in SP games, but instead increased it.
Sony first party was literally setting the bar with virtually every single game every single year. Order 2015. Uncharted 2016. Horizon 2017. GOW 2018. Death Stranding 2019. TLOU2 2020.
