Anyone who thinks that Sony doesn’t care about PS+ cancellations is seriously mistaken.
Every company nowadays has very strict and optimised accounting. Profit margins don’t just flow into manager accounts, they are part of long-term Investment plans and are being budgeted precisely. Take the high component cost of the PS6, it’s probably partly of what made Sony make this radical decision. If a certain number of customers suddenly walk away, it might mean more loss than they had originally anticipated. Also, looking at the current state of the gaming industry, they are in trouble. It’s a fact. They’re counting on the largest part of people to return, once the backlash calms down.
They want to make you believe they don’t care, in order to discourage you.
