Is it quite like that though? Isn't it more like:
Shop Owner: "Oh hi, DBT, good to see you today. I just got a shipment of X in, but not as much as I ordered, and they are selling like hotcakes. Anyway, I saved some for you because I knew you would be in today, and I know you really like X, so I've sent a letter to your house, and to your friend's houses, and anyone you've ever met who seems likely to want X, to let you and them know."
		
		
	 
  
	
	
		
		
			DBT: "ok, thanks, I don't actually want any more X, but...... how exactly did you find out my address.... and come to think of it the addresses of my friends?."
		
		
	 
Let's finish that conversation, shall we?
	
	
		
		
			Shop Owner: Um, you told me your address when you wanted X delivered and then you consented to let me see all of your friend's addresses when you set up your profile on Facebook.  And they also consented to let me see their addresses and send them letters too.  But, relax your fucking crack, because it's just a letter offering them a discount on X and if you or they don't want that again then they can simply click the "unsubscribe" button and poof, it goes away.
		
		
	 
But, you know, that's not dramatic, so...
	
	
		
		
			I'm not saying the shop owner in that scenario is the embodiment of pure evil, obviously. I'm just saying it was not quite the same back in the day.
		
		
	 
You're right, because "back in the day" marketers had to send EVERYBODY IN YOUR TOWN the same catalogue and the same "junk" mail that had nothing you'd want as opposed to today when they can send you specific discounts on ONLY the things that you most often purchase.
OHMYGODHOWHORRIBLE!
But, but, but, they know your  address!

And now we slip into equivocation.....
[quote]who might want to exploit your predilection for X, or something else they know about you, to try to manipulate you in other ways[/quote]
In "other" ways.  So, because you like Crest toothpaste; it's white; you must like white things; you're a Neo-Nazi!  Got it four.
And now within your equivocation fallacy we shift AWAY from marketing--away from using the knife to cut cake--and into using the knife for no other purpose but to slit throats...
[quote]basically so they can make shedloads more money[/quote]
How?  By trying to influence voters to change their ideological position and vote in a certain way?  So, now we have completely jettisoned anything to do with using the knife to eat cake.
And has this ever happened "back in the day"?  Wait, don't tell me; they didn't have super computers back in the day, so THAT's why it's now somehow different and not the fact that the common denominator is the fact that they didn't NEED super computers back in the day to nevertheless attempt to do the same kind of influence campaign that likely had roughly the same effect judging once again from the Koch failure to turn the blue tide in 2018 and the fact that the Russian efforts were MASSIVE and only managed to move the needle a tiny percentage (less than 1%, if in fact at all as we still don't have a clear assessment).
So, once again, blame the technology, not the bad actors.  That's the way to stop these things.  Don't deal with the intent, just demonize the tools.  The knife is to blame!
[quote] (and they like having certain politicians in power who will let them do that much more easily[/quote]
And now we've gone from a very large circle in the Venn diagram of fever dreams down to an extremely small circle of bad actors that has ZERO to do with marketing.  
[quote]and we don't even need to specifically get into some of the ways they might want to make the extra shedloads of money[/quote]
No, of course not, because that would completely deflate your boogeyman.  Oh, like what you did here in this blatant series of false equivalences:
[quote]such as by being allowed to increase profits by cheaply polluting the environment[/quote]
So, marketing is to blame for a company polluting the environment.
[quote]or shortchanging workers[/quote]
So, marketing is to blame for a company short changing their workers.
[quote]*snip gross ignorance of what actually happened in the mortgage crisis* or selling bombs to people who will drop them on civilians[/quote]
So, marketing is to blame for [i]war crimes[/i]. 
[quote]and we also don't necessarily need to assume they'll necessarily be telling lies to you, your fiends and everyone, but it is a distinct possibility) then things might take on a slightly more potentially sinister complexion.[/QUOTE]
Well, then, by god, you'd better kill all the marketers because that's the only way you'll stop war crimes from occurring and companies shortchanging their workers and companies polluting the environment, because none of that every happened "back in the day," right!!??
You've posted some mighty insipid nonsense before ruby, but this is truly impressive.  Congratulations.
