Well in this case the user wouldn't be reading or accepting any EULA, because this 3rd party site doesn't provide any such things with the firmware it is re-distributing. IOW, the only way the user can use this device is to download the firmware from this 3rd site & ignore the lack of legal information they provide about license/distribution rules.
