As a software dev, I don’t think there really is a better way. One thing you could do to avoid this is to install a second drive and boot to completely different OSes. You could boot to a Linux drive for personal stuff, and only use Windows for gaming.
These gaming companies are pretty aware that they go bankrupt if they either get a reputation for abusing anti-chrst data OR are full of cheaters. They have some incentive to use data ethically. But it’s still a good thing to keep an eye on.
Wanna bet? There are ways to frog in a boiling pot this. And chrome isn’t the only browser that will support blocking Firefox. (They’ll argue Chromium is not Google, only Chrome).
