I'm amazed that this case succeeded.
My view is that if the WiFi access point owner doesn't restrict access to listed wireless clients (such as by MAC address), then that is tantamount to inviting open access.
In my local town, businessmen have set up a free WiFi AP for anyone to use. I haven't tried it yet, but I understand that there is a homepage with some local advertising which appears first, from which users can proceed to the Internet.
