- Adobe's proprietary RMSDK engine, used by Kobo, fails to handle modern CSS like the min() function, causing valid EPUB files to be labeled as corrupted without clear error messages.
- Epubcheck validation confirms EPUB compliance but cannot detect renderer-specific issues, highlighting a gap between standards validation and real-world compatibility.
- The digital publishing industry prioritizes DRM and control over user experience, leading to outdated rendering engines and poor error handling in widely used e-reader software.
