I have always had a bottle opener keychain [1]. When grabbing it from my pocket it is easy to tell by feel which way is "up" (flat side for me) so they keys are always oriented correctly. The keys can't "loop" around, either, so the order is guaranteed. It's also a useful tool.
They didn't intend it, but they should have since they'd probably end up with a better end-user experience ala Rockbox/LineageOS. The community added some cool features and worked around some glaring bugs until Mazda clamped down by specifically nuking the mods on updates. God forbid anyone embarrass them by making their crappy software better, like pausing a stream when "Mute" was hit instead of letting the stream run while muted. How about this? If you used a USB stick full of music it showed the files in FAT order, not sorted by filename or ID3 tags. It would also just randomly forget the resume point, and revert to playing the "first" file on the disk. So instead of Amon Amarth blasting my ears in this case, I had to both create a file named "0000Silence.mp3", and run a special command after every disk update to rewrite the FAT so the FAT order equaled alphabetical order.
From the posted notice[1], they answered "No" to the question "Do you claim to have any technological measures in place to control access to your copyrighted content? Please see our Complaints about Anti-Circumvention Technology if you are unsure." Is that the same thing you are referencing?
