Thanks – that’s an announcement about policy updates. I already read it and it says nothing about fingerprinting. The only change to underlying technologies it mentions is the use of e.g. trusted execution environments (the doc for which, per a further link, is in fact on github). Those seem to claim that they let announcers run ad campaigns through Google ads while keeping their campaign data provably locked away from Google. So, basically, all these links are about purported “privacy-enhancing” techs, and you’d be forgiven for taking that with an enormous grain of salt, but either way, nothing in there about fingerprinting.

The Guardian article basically paraphrases the Tuta one – or it’s the other way around, maybe – but does also not provide actual sources.

I just want a source on what fingerprinting Tuta is claiming Google will start using. I feel like the details of the purported fingerprinting techniques should be front and center to this discussion and I’m frustrated that the article entirely fails to provide that info.
