Nice story, but this is where it falls down in my head. The online mentioning that triggered the gift was the desired model. I’d say that has an element of choice, similar to you picking a guitar up in store.
As above, no prompt as to receiving a gift but a prompt online as to what you wanted even if not directed at your friend.
There’s still room for interpretation in the rules that allow it to be judged on a case by case basis. The jury has spoken on this one!
