I share your concern about using the correct word(s) to describe what
is going on. That "tuner" is, indeed, an impedance matching
device/network, whose purpose is to present to the transmitter a load
with which it is "happy" to supply full power.
Likewise, I reject nearly all uses of the words "balun" and "ground,"
because they have multiple meanings that nearly always lead to
confusion, and to hams doing really dumb things. I also object to the
phrase "ground loop," which is a totally false concept, and also
causes hams to do really dumb (and wrong) things to solve real world
problems.
Call it what it is -- that "tuner" is an adjustable matching network,"
at least a dozen different things are described by the word "balun,"
and many uses of the word "ground" have nothing to do with a
connection to mother earth.
