This is about cookie banners on websites
There was another time I got into a very serious ontological discussion with a fairly senior engineer about what the difference was between taxes and fines and they didn’t understand there was a difference,” he said.


Your ISP and browser can see everything you do, but your search engine can only see what you’re doing when you’re actively on the site, and through cookies. Same with those other sites. Using incognito absolutely helps with that.
That’s plain false. With a VPN enabled, the ISP can see data volume and time stamps, and what VPN server you’re connected to. Nothing else.
Your browser, depends on the browser. Chrome, Edge, etc., yeah, they’re watching everything you do. An open-source privacy-focused browser with maximum privacy settings enabled is not watching as much, if anything at all.
And incognito doesn’t hide your fingerprint from search engines or websites. It’s basically worthless for privacy. All it does is clear cookies, caches, and browsing history from the local device.
I was talking about this statement:
Obviously if you use a VPN your ISP can’t see it.
If you use a private browser they’re not watching you, but again, your browser can easily log all that information if they are inclined to.
I didn’t say anything about fingerprinting and neither did you. Cookies are a large part of tracking, I never said it was the only way they’re tracking. But if I go on one site and they fingerprint me, and then I go on another site and they fingerprint me, the first site doesn’t automatically know I was on the second site because of the same fingerprint. They would know because of the cookies.
