It's explained elsewhere in the book:
> Fame has a dark side. When Times New Roman appears in a book, document, or advertisement, it connotes apathy. It says, “I submitted to the font of least resistance.” Times New Roman is not a font choice so much as the absence of a font choice, like the blackness of deep space is not a color. To look at Times New Roman is to gaze into the void.

Its a pity the author doesn't explain why.
For some reason times new roman looks very good printed but is not very well readable on screens. Personally I don't like Arial much. A big no no is the capital i being indistinguishable from the l of lima.
