A web page that tells you what your browser gave away the moment you arrived. No login, no form, no permission. Most pages do this. None of them tell you.
The only thing in there I find surprising is the battery info. I’m not sure what legitimate use a website would have for that one. And perhaps that the gyro isn’t behind a permission. There’s pages that use it for 360 video for example, but you should have to allow that one.
Your IP address is a fundamental part of communication over the Internet, obviously the servers you speak to are going to need to know where to send their replies. There are ways to mask that ofc; proxies, vpns, etc.
Timezone+Language are needed for localization.
Display information and preferences, to render things correctly/as desired. Desktop web pages look like crap on a mobile display (and what type of mobile? Tablet, or phone?), plus they can’t (well, shouldn’t) show things in darkMode unless you tell them that’s what you want…
Cookies: it does say 0mb stored by others for me, but that’s not entirely true. Sites are typically given independent storage so they can’t read eachothers cookies, but they can work together to have one site read its own cookies and pass that on to the site you’re currently visiting, on request, all embedded in the original page you were viewing. Just because they can’t read eachothers storage directly doesn’t necessarily mean thay can’t get the data. 10gb per site seems like an absurdly high limit for this though. You could store whole movies in that space.
Visibility is one I’ve known but never really liked. The only ‘legitimate’ use for that I’ve seen is pausing media when it leaves your screen (or waiting to start media until its entered view), but half the time that’s undesirable anyway. Why should a site know if, when, and how long I’ve looked at a particular portion of the page?

re: visibility Some sites have heavy visual effects that are paused when you tab out, which is a good use of the feature.
