Thanks for that. I can't read the article, probably because I block WASM (and Javascript) for security. None of my ebook readers have Internet access (for security and for privacy), so none of those internet-only epub files would work for me.

This might be "legal", since XHTML was intended for the web, but I assume Google's using it to collect more user interaction data that they can sell to data brokers.

FWIW, PDF is simply Postscript that's been compressed. As far as I can tell, almost all documents these days are created with Microsoft Word, TeX, or Postscript. I'm lumping things like PageMaker and LaTeX in with the base they were derived from.

The article is a WASM EPUB viewer. There's a link shown in the viewer to the EPUB file:
