Electronic Airport Facility Directories ("A/FDs")

I'll start with a rant; it's disturbing to find that the Department of
Transportation ("DOT") does not release the AFDs in a useable digital
format.

The DOT cannot legally copyright the AFD, so AFAIK anyone is free to
tear the binding off, scan it, and redistribute it. Is anyone doing
this?

Airnav.com is useful, considering it's the closest thing to a
publication of similar information (and non-raster, which is even
better). However, the keyword is "similar". Airnav makes no
guarantees about providing the same information as the AFD. Can a
pilot legally use airnav's publications instead of the AFD, and still
be compliant with FAR 91.103?

I would guess not, considering the Airnav's caution about the currency
of the information. Any case law on this?
