There's a difference between ignoring the market and saying in the next 2.5 years we're launching like 12 games in the category.
People are hopeful Sony doesn't go all in on this but I remember a time when Sony made games like Sly Cooper, Jak and Daxter, and other mascot games. Now the only one left is Ratchet and Clank. As more people start buying into these live service games Sony will gravitate towards that just like they gravitated towards making those single player third person cinematic action games into the PS3 and PS4 era.
The fact that they're talking them up so much is what's so disturbing. It's shareholder pandering and letting what they shareholders want (games that focus on monetization most) dictate direction over what the fans like.
It's what happened to GTA. Why bother making another story based DLC when online expansion packs print money? Plans get abandoned and you spend a decade plus with GTA V existing as a platform for it's live service aspects. From GTA IV to V was about 5 years or a normal development cycle. GTA V has existed across 3 console generations as the only mainline title. In that decade GTA VI still hasn't been finished.
These live service games transform companies.
