I'm not sede personally, but my guess would be the huge font, as well as lack of indentation and proper spacing between paragraphs. As one gets older it is very difficult to read. Even with progressive lenses.
Nope: I always supply the link, by which the sedes can read the article in its native font.
I have another idea:
A pope who is not always infallible, and who can give evil commands, is fatal to sedevacantism, therefore they prefer to wait for the article to be buried.
