In July 2020, out of the blue, without any warning, my Apple ID was also locked for unspecified "security reasons." I kept getting redirected to a page on appleid.apple.com to unlock my account by supplying answers to various security questions, but it always ended in failure. Also, some of the time I was asked to supply a recovery key.
As a result, I lost access to my entire music library, which I had begun collecting digitally in the late 90s when iTunes first came out and ripping and organizing MP3s become common and easy. I ripped hundreds of CDs that I had been buying since about 1992. After the iTunes Music Store launched, I even bought probably $300-$400 worth of music over the next 10-15 years. At some point, I subscribed to iTunes Match so that I could get all my stuff uploaded to the iCloud Music Library, which to me seemed awesome because suddenly my whole music collection was available on my iPhone without having to sync it manually or having to pick and choose the stuff I wanted synced, and also available on multiple devices. Eventually I switched to an Apple Music subscription. All the while, in addition to purchased iTunes Music Store tracks and the stuff on Apple Music that I had added to my library, there was also all of my ripped CDs, as well as a fair amount of content I got elsewhere (downloaded from various places—a lot of it was stuff I would never be able to get again because it was, say, DJ sets that I could no longer get from the original place). All of this was either uploaded or matched into iCloud Music Library, and this worked flawlessly for several years.
I also lost the ability to use iMessage, all of my App Store purchases were now dead-ended and not updatable, and thanks to the Find My/Activation Lock system, I was not able to sign-out of my Apple ID/iCloud account on my iPhone, and thus I couldn't set it up with a new one, and thus iMessage and the App Store and various other features were just dead to me. I basically had to go to Sprint and report my phone lost/stolen to get a replacement phone ($150 deductible in spite of paying $15 a month for their insurance for years). A little while later, I managed to figure out a way to bypass the Activation Lock (not sure if I discovered some sort of bug/exploit or just an obscure, non-advertised method) and consequently I was able to wipe the phone and theoretically I could get it carrier unlocked and put a new SIM in it and perhaps use it again or possibly sell it, though I haven't tried to do any of that stuff yet.
I was also using the iCloud Drive (Desktop and Documents) to store all of my data, and also storing all my photos on iCloud, but thankfully all of that was data still also lived on two laptop hard drives so I didn't lose anything. Also, bizarrely, though I had been using iCloud Keychain, somehow all of that data was also preserved on one of the laptops and after I got it setup to use a brand new Apple ID, it picked all of those passwords up again for me.
Probably for me the most traumatic loss was that of the music library. Yeah yeah yeah, I should have maintained local copies of everything, BUT it was like 400 GB of music in total and my MacBook Pro only has a 128 GB SSD and it was already usually fairly full even without the music. Trying to connect an external drive and pointing iTunes/Music to it and clicking "download" for everything would have taken DAYS (at least) to download everything, and since I was constantly adding new stuff to it, it seemed like it would always be out of date or I would have to maintain that backup version all the time.
Anyway, I have always been very fastidious about keeping all of the info for any 2-factor authentication schemes I have enabled (recovery keys, backup codes, QR codes, etc), and I even had one labeled "Apple ID recovery key", however it was a 14-character key from an earlier era before Apple implemented their iCloud-based 2-factor authentication system, and at some point whenever they moved to that system, they also moved to 28-character recovery keys, and somehow, completely inexplicably to me, I never seem to have saved that key anywhere.
I was so upset and angry and frustrated that I ended up getting an attorney friend to write a strongly-worded letter to somebody I found on Apple's executive leadership page, and within 24 hours I was contacted by someone from Apple (different person) that I spent like 10 days interacting with trying to get this fixed, but in the end, they were pretty much (a) never actually managed to explain WHY my account had even been locked to begin with, and (b) basically said that once an account had enabled use of a recovery key, it was impossible to undo that AND it was technically impossible for them to unlock it or access it or do anything with it. I also had to cancel the credit card that it was being charged to, because they claimed to not even be able to terminate the account or at least terminate that particular billing method, and the only way to get it to stop was by cancelling the card completely. But the account still lives on, because I still get weekly emails from when I was signed up as an Apple Developer, and occasionally I get other stuff, all addressed to that particular email address (which was not an Apple-provided address), and I am basically powerless to stop it.
I was so very upset when this happened that I wanted to shout about it here and anywhere else I could think of that would have an audience, but I eventually just moved on.
I'm not sure how anyone could amass $14,000 worth of irreplaceable digital DRM'd content, but I can certainly sympathize with this person, and I hope his lawsuit at least causes Apple to consider redesigning some of their security systems to make situations like this not as fatal.
Don't really want to get into the whole walled garden/DRM/cloud vs. local debate. Yes, I made some mistakes in my setup, and those have been corrected going forward. But this is still a very shitty thing for Apple or any other large company to do to a customer with no recourse, and it is absolutely very traumatic.
