(actually jailbreaking and downgrading would be sufficient, since after that I could just not connect it to wifi). What sort of people would be able to do this?

Thank you again everyone, I have read your messages attentively, and hopefully my previous reply (and this reply!) will appear soon.
Roughly speaking, you'd need to:
  • Find a device compatible with KindleBreak
  • Jailbreak the device and install the hotfix + Cowards Rescue Pack
  • Extract the rootfs.img from a suitable firmware version using KindleTool (I have a feeling that the DL links for old-old firmware versions were removed by Amazon but the rootfs.img from a Factory image would work)
  • Transfer the rootfs.img to the Kindle USB userstore
  • Boot into diagnostics mode and login over SSH
  • Flash the rootfs.img to the main firmware partition
  • Disable OTA updates by https://www.mobileread.com/forums/sh...d.php?t=327879 following this thread

There's a thread with more info about downgrading with this method here.
