You’ll end up with a fork of Chromium/Blink that doesn’t have WEI. And it will be used to surf web sites. While the official browser from Google would be used to access sites that require WEI attestations. Just like the Bank of America app would.
Corporate power in pushing Chrome for everything can be limited if we have open source alternatives. Look at Firefox and what it did to M$IE, which had the full power of Micro$oft behind it. That only happened because Netscape chose to OPEN SOURCE their code base. They couldn’t beat IE on their own, but the open source community could.
Well, that and WebKit, which was basically adopted by Apple (Microsoft’s competitor) from another open source browser, Konqueror! And that led to Chrome, Chromium and Blink etc.
In short — open source is the best way we can check corporate power on the software side.
On the hardware side, it’s far more difficult, and if the vendors choose to ban any “unapproved” apps (eg requiring Safari WebView rendering engine in all apps on non-jailbroken iPhones) then the best tool we have is government antitrust laws. Maybe one day, in that area too, open source hardware will be the people’s best weapon. But not today :-/
