Cookies can contain fingerprints, but they’re also used for a bunch of other things, like keeping you logged in, remembering your shopping cart rather than clearing it every page load, storing preferences, remembering if your device has a high DPI screen (so a fresh page load knows to serve higher quality images), etc. Anything where small amounts of data have to be persisted and shared across both the client-side and server-side. They’re not always evil.
If your device has a high DPI screen, I would hope they would be able to determine that each time rather than have to take up storage space on MY device recalling that fact.

Well, yes, of course, but the context here was the evil kind of cookies.
