Yes, there is confusion. People speak of TeX and pdftex both
generically and with reference to the particular command tex or
pdftex. The particular commands include plain tex in both cases.
When I say pdftex I mean the program as distributed, with the
plain tex commands included.
As a result many people who use LaTeX or pdflatex use the
generic term TeX or pdftex when they really mean the LaTeX variants. But
after nearly four decades I don't think the use of the same words
to mean both the generic engine and the plain tex implementation
thereof will change.
TeX can mean the base engine, or TeX + plain.tex or even TeX
plus Latex. Blame it on Knuth.
