I think Valve should really make the current „Betas“-Feature more prominent, and rename it to „Versions“ or something. It should* be pretty easy for Firaxis to just offer an old, cross-play enabled version there, while updating the regular version more frequently on PC. That would make disabling such features unnecessary.
I’ve seen only a few developers actually making use of „Beta“s in that way, but I think it would be very useful in cases like this.
* there could, of course, be other technical issues preventing them from doing that, which only their developers know of
Edit: They’ve actually added a console-compatible “Beta” yesterday.
I unfortunately can’t really see how a browser could still be nice to use and properly resist fingerprinting.
The site https://amiunique.org/fingerprint tries to fingerprint your browser and lists the used attributes along with their uniqueness within their dataset. And while a browser could pretty reliably lie about its User Agent or Platform, it’s often just necessary for a modern website to know, for example, what your view-port’s resolution is or what kind of audio/video codecs your device supports. Going through my own results, I’d say combining these necessary data points is probably enough to identify me, even though I’m pretty privacy-conscious.
Maybe I’m overly pessimistic, but I think preventing fingerprinting would need a regulatory instead of a technical solution. Unfortunately that doesn’t seem very likely anytime soon.
