No, the licence doesn't extend to those users. If it did, you'd be
having to provide the source to all your GPL'd apps as well when those
users took copies of the binaries on your system.
You have no obligation to those users at all, "not giving them a copy"
does not count as "obstruction". In order to infringe that section of
the licence, you have to first have an obligation to someone, and then
also fail to fulfil that obligation.
I think it's probably a valid criticism that the FDL doesn't allow dual
DRM'd/transparent distribution, but I don't necessarily think that's a
freeness issue (I don't see any practical problem arising from that
situation, but could be convinced I guess). I don't buy the other
criticisms of the DRM clause; they don't seem to stand up to scrutiny.

Let's say it was "make and distribute". If you had manufacturer A, who
published GFDL'd books and supplied electronic copies to person B, that
person B could modify those copies to be DRM'd and redistribute those
modified copies. They only way you could stop that would be to argue
that person B is "making" copies rather than "modifying" them, but that
sounds shaky to me so long as person B isn't the one doing the copying.
"Make or distribute" keeps the flexibility of that section, and I think
the FDL does a great job of "copylefting" the anti-DRM provision, as it
were.
Cheers,
Alex.
