I think the point is that you don’t have to pay ANYTHING per month to play apps or games you already fully paid for online whereas not paying for playstation online means you lose that entire aspect of your own device whereas with a ps5 if you stop paying sony you can no longer even use netflix despite paying netflix your isp and sony for their hardware. They use the fact that they control your device to effectively blackmail you by making third party apps contingent on paying their blackmail.
