right? Acrobat does not handle this anti-aliasing (if it is that)

Yeah, if a line is too thin to cover the width of an entire pixel,
antialiasing is the answer. It's basically the same as rendering it at a
larger size, and then scaling down with interpolation.

Yes, this sounds like what is going on. The Guardian either does
not know about this or are not prepared to give advice...
(perhaps they have commercial reasons not to badmouth Adobe?)

Well, antialiasing wouldn't be needed if they just made their lines a little
thicker so they fill a whole pixel at sensible levels of zoom! I'm sure
this is *easily* within their powers.

I suppose this being the Guardian though, they're more interested in the
look on the printed page. Can I really be the only person who prefers the
less colourfull, non-design award winning old broadsheet over the fancy
new "Berliner" format? When newspapers come on electronic paper I hope
there's some equivalent thing to overriding their CSS.

They are aware of the problem. And cheerfully note that the
problem is not evident in printing. I rarely print them. I use
the spare blank side of old A4's that have been printed with a
nice big grid and jot the numbers down with a pencil. It is not
hard to guess the lines...
