Agreed. It's not a "fingerprint" at all as in most cases, it won't be remotely unique. For example: every user in the world with the same screen size, browser & platform will get the same result. For desktop it's window size rather than screen, but coarsely bucketed. Thousands or millions will share the same fingerprint. It seems somewhat unrealistic to ascribe much advertisement or tracking value to this.
