If it that was their basis, I am reasonably comfortable that an attorney, electrical engineer and a competent mechanic's testimony would refute their claim.

Exactly as MlwYlw stated, any number of things plugged into that port will prevent OnStar from running diagnostics. After a mouse attacked my 2006 GMC pickup several years ago I got the same OnStar "unable to run diags" email two months in a row due to a blown fuse. And OBD-II code reader plugged in when OnStar tries to run monthly diagnostics will create the same "fault".
There are a lot of things you can do which will kill your warranty but an email to the owner because OnStar couldn't complete diagnostics isn't one of them.

OnStar is speculating that " This issue may be caused by an aftermarket device plugged into your vehicle's diagnostic port. " It could be one of any number of legitimate OBD II devices that could be used at any given time, as mentioned above. They don't know for a fact that a Range AFM disabler is being used as it leaves no electronic footprint.
I'm comfortable that there will be no negative issues regarding the vehicle's factory warranty as a result of using the Range device.
