Honestly now I'm not sure what he meant by Marketing. I still think he meant "getting the word out" Which would fall on advertising in all it's lovely forms.
I think you’re using “advertising” the way a marketing person would use “marketing”.
I don't think this changes anyone's point, just clarifying what might feel pedantic where there is a term of art associated.
But even in advertising, there's a huge variance of ethics. I don't love targeted advertising based on my search history. I'm perfectly fine with my favorite history podcast being able to continue because of casper ads. In that case, casper isn't tracking me specifically... just assuming that history podcast listeners might be good mattress customers.
To be even more precise (or pedantic), "getting the word out" (aka generating awareness) in general is called "Promotion." Advertising is a form of promotion. So is "word-of-mouth" and public relations (aka press relations). All of them fall under the broad responsibility of "Marketing."
