I don’t see in what way having a PSN account would make Horizon Zero Dawn safer on PC.
It’s safer for Sony’s stock price, as they can report higher numbers of people on the PlayStation Network and greater “player engagement”. What, you thought this was about improving the experience for the customer? No one gives a fuck about them.
Na, my experience is that Defender is fine with users downloading browsers and “updates” from random Russian sites. It’s happy to let the users install that software and only bothers to log a “hey, maybe this was bad” alert some time later. Edge, on the other hand, loses it’s shit when you visit the official download sites for Chrome or FireFox.
