Aka corporations insist on control & want to make sure users are powerless when using the site. And Chrome is absolutely here to help the megacorp's radically progress the War On General Purpose Computing and make sure users are safe & securely tied to environments where they are powerless.
There's notably absolutely no discussion or mention of what kind of checks an attestation authority might give, other than "maybe Google Play might attest for the environment" as a throwaway abstract example with no details. Any browser could do whatever they want with this spec, go as afar as they want to say, yes, this is a pristine development environment. If you open DevTools, Google will probably fail you.
It appalls me to imagine how much time & mind-warping it must have taken to concoct such a banal "user motivation" statement as this. This is by the far the lowest & most sold-out passed-over bullshit I have ever seen from Chrome, who generally I actually really do trust to be doing good & who I look forward to hearing more from.
These are mega corporations and you aren’t the client. They aren’t making Chrome “for you”. They are for optimizing for Advertisers.
Generally I am pro Project Fugu & pro building bigger better web. Google spends an enormous amount of effort working on specs with w3c, wicg, and other browser implementers advancing incredibly good & useful causes. They spend huge effort enhancing DevTools so everyone can work the web.
Building a good & capable web is necessary for Google to survive. An open & capable web is the only sustainable viable alternative the world has seen to closed proprietary systems, which from history we can see have far more risks hazards & entailed pernicious or particular behaviors.
Generally Googles effort to make the web a good viable & healthy platform aligns with my vision. That they want to do good things & make a great connected world wide web because the web's thriving helps them run their advertising business typically does not create a big conflict for me. I'm usually happy with the patronage the web receives & I dread it ever drying up, and it saddens me people are so monofocused, so selective in focusing on only on bad, and I think that perception hurts us all.
