Thanks for explaining. From previous looks at this website, I did not consider it an electronic transcription but an embedding of the original PDF; a closer look reveals some differences in this case (the image at the side of the first page has disappeared, and the subheading / pullquote at the top of the first page has been retypeset somehow). Apart from that, all the line breaks and character positions seem to match, so it does appear to be identical to the canonical source. The other reasons make sense (it didn't occur to me that it may not display properly; my understanding of their technology was that they simply took the original PDF and added dots as markers; I hadn't noticed that it wasn't downloadable).
