This happened to me really early on when my original Apple ID had an invalid format, as it was an ID made prior to the current version of Apple ID everyone uses, and Apple refused to port what I owned to the ID that I was forced to generate to sign into my newer device. My old ID had software no longer available in App Store, so this wasn’t just a matter of needing to repurchase apps- they were taking away my ability to use applications I bought from them. Since then, I’ve been incredibly wary of losing my Apple ID. I have a lot of respect for Apple, but I would bet that it’s easier to deal with ID related problems for someone with Q level clearance in the U.S. government or even a non-existent Men In Black ID problem than to resolve a problem with an Apple ID. They probably would tell the almighty to get a new ID.
