I think the foobar practice should be avoided even in
abstract "examples" because

1) It is often so that the examples get worse by this
   habit - instead of real-world examples that might
   take a couple of minutes to make up/find, but are
   better in most cases, as they provide the example
   with some context, which makes the principle easier
   to understand, but also in the bargain shows some
   (other) aspect of the system and how the principle
   is typically put to use. (This is the same method
   the good old school grammar books used. There were
   a lot of abstract reasoning with word classes and
   phrase analysis but then came examples with
   specific phrases and you'd realize the theory but
   also learn them phrases at the same time!)

2) If you do the foobar stuff in examples too much,
   that will eat its way to real use soon enough.
   The people who write it, or read it, or Google it,
   it doesn't matter, one way or another it is always
   like that.

What to name things in programming is a big part of
what makes for good code and bad. People may disagree
what is a good name and what is not as good.
But follow the simple principle that everything should
be named after its functionality and/or unique
properties (in the context) and it won't get that bad.
If it works, and everything is named according to this
principle (even badly so to some people) I don't think
anyone will have a case "the style is bad". A single
foobar tho is instant DQ.

Most important it makes SENSE for things to be named
sensibly. Without that there is chaos. And not chaos
as in the jungle which actually is chaos only to the
untrained eye lacking the fine touch to decipher the
(sub)systems - it is chaos as in the mad dreams of
winter vomiting disease.
