This argument could for any question, like "Do you trade options, futures, stocks, or bonds? And saying "Nearly all of the choices are a type of instrument." True, but uninformative.
I think price action alone via charts should be a different poll option than price action alone via the T&S and order books. I trade off the prints and books, not charts.
I think those who think they are trading off of price action alone are actually employing TA on some level, whether they are cognizant of it or not. So I would argue that price action is a subset of TA.
