This is not misuse. Everyone in signal processing knows what decimation means in this context.
I pulled out one of my older signal processing books - Gold and Rader, "Digital Processing Of Signals", 1969 - and Decimation is used in several places exactly as we use it today. I looked in some of my non-digital signal processing and older books, like MIT Rad Lab series, and don't see the term used, but I know that I heard old-timers using decimation used in automatic analog signal processing especially with regard to "zooming out" on a spectrum analyzer or pinball-style pulse-height analyzer (often the knobs gave you only factors of ten).
