Very relevant, IMHO. I don't want to hear "think of the children!1!!11" as an argument against patents any more than I do for or against anything else.
In this instance however, it is think of this very specific child. There is no hypothetical child here who might be harmed. There is a real, actual child who will lose her ability to communicate if this app is pulled off and remotely deleted from her iPad.
When Apple yanks apps from the store, they are not remotely deleted from customer's iDevices or PC's. There are a small handful of cases where remote deletion was used, and IIRC, it was all various forms of malware.
