Sanctuary is a simple jailbreak tool for (some) Kindle devices

Sanctuary is a new jailbreak tool designed to give some Kindle devices more flexibility by allowing users to read eBooks in unsupported formats and offering enhanced formatting and display options. While Kindles are locked down to mainly read Amazon-approved content, Sanctuary breaks through some of these restrictions, enabling a broader range of reading experiences. This development matters because it empowers users who want more control over their reading devices, potentially saving them money on proprietary formats. However, it's worth noting that this tool only works for certain Kindle models, limiting its immediate impact.
