> it’s not clear how this reduces control of your own computer. It eliminates a computer user's ability to have their user agent lie about the platform it's operating on. Such a capability is crucial for privacy and adversarial compatibility. Simple example: your bank of choice starts sniffing your UA string and refusing to serve Firefox, as they only test the site in Chrome and don't want to service support tickets for any other browsers. Presently you can spoof your UA string and visit the site with Firefox anyway. With WEI the bank site now has the technical means to ensure your browser accurately reports its identity and to refuse access to anything but Chrome. I'm not necessarily claiming that this is how WEI will be used, but the point is it's now up to site operators to choose what makes a valid visitor, rather than the UA being just a transparent medium between you and a website (provided that each is implemented to spec).
