No it would be cloudfare. That’s their whole business.

So, for example, right now if you visit a website using cloudfare as their CDN, and your browser looks “suspicious”, cloudfare will grab you and redirect you to a verification page to put a captcha in to verify that you’re human before they will direct you back to the website you’re trying to go to. That’s why people use cloudfare in the first place instead of trying to implement some verification themselves. It’s easier and cheaper to outsource to a specialist.

Attestation would just be a “fast pass” for users. If your browser looks “suspicious” then you would be redirected to cloudfare for verification. Instead of a captcha though, it would automatically negotiate with your browser that would present a token generated on device to cloudfare. Cloudfare would reach out to the attestor for that browser with that token to validate it. For safari it would be Apple, for edge it would be Microsoft, for other chromium browsers it would be Google. The attestor would look at the token and be able to say “yes this is a valid, unmodified version of macOS/Windows/ChromeOS/etc and likely to be a normal human” and you would be directed back to the website you want to go to instead of having to put a captcha in.

The danger is when these companies start to control attestation. If you have a modified OS? Sorry we don’t know if they’re human. And you’ll have to enter a captcha. Potentially, if your phone/machine is not the latest version? Sorry don’t know, enter a captcha. Using lineage instead of a licensed version of Android (like Samsungs skin, etc), sorry not validated, enter a captcha.

If attestation becomes mainstream, then it will be the default because it’s cheaper for the CDNs and everyone to do. But it puts the power in the hands of like 3 companies for attestation. And it’s very very likely they will start limiting attestation as a “feature”. Have a galaxy phone? Well if you haven’t upgraded in a few years and are no longer in recurrent supported devices list, sorry no attestation. And they only offer like 3-4 years of official support. So if you don’t want to enter a captcha every time you change webpages, better upgrade homie.

So naturally it will push your average consumer to just upgrading a perfectly fine device instead of keeping it. And it will discourage a ton of FOSS stuff because that will all be “unvalidated modifications” or won’t implement it. If Google implements it, that will be the nail because chrome has like a 70% market share and pretty much everyone will develop for that. So they’ll all develop with Google’s attestation in mind. If you’re using Firefox which won’t implement it, you’ll be entering a captcha every time. And that will push people over to the big companies.

Attestation is a MUCH bigger thing than people think. You don’t need to worry about every website implementing it. You only need to worry about like 3. Cloudfare and Fastly are two huge ones, which have already implemented it on an as available basis. Right now it’s just Safari but they have it available if Google and Microsoft implement it.

Google themselves are the third one since the way operate their own CDN for themselves and clients. If they implement attestation there will be immediately a huge chunk of the web using it. Like 70%+. Cloudfare has 20%+ of the market and Fastly is like 18%. Google makes up another huge chunk but I couldn’t find any figures.

That would be such a huge immediate usage that it would very rapidly become the default and would lock people into only the big companies.

^Instead it transmits a list of running processes (or other, formerly private info).

No it doesn't. Attestation is simply a cryptographicly signed "we trust this user is human" message.

Ehh, way to miss the point. This article is about Apple, but Google is doing the same with Android and Chrome.

Parties that have issues with this are Linux distros and browsers like Firefox, that leave control and "humanness indicators" more in the hands of the users, instead of in the hands of big, influential companies.

If you go to a cloudflare hosted site and it thinks you might be a bot if your browser supports it it'll skip the captcha. The point of it is that you don't notice it. Here's a blog article on it from them: https://blog.cloudflare.com/eliminating-captchas-on-iphones-and-macs-using-new-standard/
