Ok, let's go through this 
again, but we will start with your quote's last line in regard to "Personal Data" (from the post before the one directly above as you evidently posted yours at the same time I was crafting this one):
	
	
		
		
			Personal data can be contrasted with data that is considered sensitive, valuable or important for other reasons, such as secret recipes, financial data, or military intelligence.
		
		
	 
So, on to what your source is calling "personal data":
	
		
			
				DBT's source said:
			
		
	
	
		
		
			Personal information or data is information or data that is linked or can be linked to individual persons. Examples include explicitly stated characteristics such as a person‘s date of birth, sexual preference, whereabouts, religion, but also the IP address of your computer or metadata pertaining to these kinds of information. In addition, personal data can also be more implicit in the form of behavioural data, for example from social media, that can be linked to individuals.
		
		
	 
As has been repeatedly explained to you, marketers don't ever see--or need to see--such data, much less buy it.  Nor, for that matter, do service providers like Facebook or Google.  They don't give a flying fuck about YOU 
personally; they only care about you in the abstract; in the data, in the demographics.  
Are you over 65?  You go into that part of the Venn diagram.  Are you male?  That part.  Do you live in X town?  That part.  Do you like fishing?  That part.  Do you buy a lot of fishing equipment every year or just look?  That part.
Then I come along and I buy an ad on Facebook for a new type of fishing rod.  So I am offered a whole host of demographic check lists from Facebook so that I can choose men, over 65 that live within a mile radius of X town who like fishing and buy a lot of new equipment.
Again, I don't give a flying fuck about who you are as a human being walking the earth; I only give a shit about my target demographic data selections.  Likewise Facebook.  I'm not out to brainwash you or read your thoughts or in any way invade your privacy--because, once again "personal data" does not just axiomatically mean it also not PUBLICLY AVAILABLE data.  Hence your own source making distinctions about what is and is not "personal data."  
If I had the time and the inclination, I could 
very easily find out how old you are; what town you live in; whether or not you fish; and even what kind and amount of fishing gear you purchase.  I could do ALL of that without a super computer or any more technology than a car, a pencil and my eyeballs without ever once invading your privacy.
Your age could easily be guessed by just looking at you.  Same with the town you live in.  By finding out the best fishing holes in the area and spending some time fishing them, I could then see whether or not you fish and what equipment you own (and its condition).  This would tell me more than enough to know whether or not you buy high end/new or old.  By striking up a friendly conversation while we both fish, I can then just ask a simple question about whether or not you're looking to buy something new as I was thinking of doing the same, but I  wasn't sure what to get, could you recommend a particular brand you like or were thinking of getting yourself, etc.
Other than my asking you an innocent question and initially asking you if it's ok that I join you fishing, I have in no way unduly harmed you or discovered your deep dark most secret of all private thoughts, but even if you had immediately told me to fuck off and I didn't get to ask you a simple question, I'd STILL be able to take your reaction as an indicator of how to market my new brand of fishing rods to you.
And that is the full extent of my interaction with your "personal data."  
Now, instead of me and what I do, Putin shows up in your town.  He's going to want a very different set of data concerning you--the kind I don't have or give a shit about.  The kind of data Facebook possesses, but does not give out or sell, so he--being a bad actor--is going to have to find other ways to harvest that information.  And he's going to use that information for a very different purpose that could not have less to do with "capitalism" than is possible to express, unless you're talking strictly metaphorically.
He's not trying to sell you--or anyone else in your town--a fishing rod; he's trying to push you off a cliff.  Or, more accurately, off a fence, since we're talking metaphorically.  He DOES want to read your deepest darkest thoughts and invade your most private of all privates (though, judging from the way you expose your thoughts on a site like this, clearly you aren't all that concerned).
Tl;dr version for morons: What Putin wants to do and what I want to do have almost nothing in common, other than, once again, we are both using the same knife (aka, "personal data").  I am using that knife to cut some delicious cake (that I hope you will enjoy and want more of); he is using the knife to slit your throat.
As to your above post, we'll conclude with:
	
	
		
		
			These considerations all provide good moral reasons for limiting and constraining access to personal data and providing individuals with control over their data.'
		
		
	 
For the last time, you already have the ability to limit and constrain access to such data.
