True. As a side point, IMHO, therapy and counseling are not products.
They’re services, and, even more so, should be a service bound by a medical code of ethics, which, since the healing professions go way back, imho makes therapy and counseling distinct from many other services.
Not true. In spanish, "ad" is usually anuncio, or sometimes comercial or publicidad. Propaganda can also be used, but is less common than those i think, I've never heard it used.
I once read an original edition of Bernays' Propaganda (1928) with its title in a jaunty typeface on the cover, before the word had a negative connotation.
"It did what all ads are supposed to do: create an anxiety relievable by purchase.”
