First of all, you’re the one to choose what you’re fingerprinting for, and if you include the battery or such changing factors maybe you should rethink your career as an engineer.

My web apps lack any telemetry, the only cookies that get set are for sessions, users settings and various redux like storage on client side which can be opted out. It’s more than proper. :)

I am not against cookie banners, I own a few web apps and each of them have proper configurable cookie settings (including the banner).

All I am saying is that most companies (especially one’s that do not reside in EU) do not care and will track you across websites by fingerprinting your hardware when visiting their website. Some do not even use cookies at all.

For the past 10 years or so tracking is done with hardware fingerprinting anyways. Cookies are of the past.
