 my brother sent his DNA to one of those stupid ancestry things, sigh

I wish people understood they share DNA with whole family so it's not exactly theirs to give out 
 Never really thought of this, thanks for opening my eyes to the idea. 
 Nephew did this too. 
 But also you are shedding your DNA all over the place. 
 Yes but it's not being sequenced and indexed for some hackers or government to steal so easily  
 Ouch, the small print on these products is generally not great... ☹️ 
 TV shows have been based on DNA results and families 
 this is an industry growing together with confidential computing. soon they’ll say it’s ok to send your DNA all around the world because the TEE enclaves get destroyed 
 I stupidly did this years ago. I had my data 'removed' but who knows how much they actually retained. 
 I was curious about it but never did it. I’m glad I didn’t 
 Never give up your DNA unless legally compelled. And even with an attempt to force you to give it up, you should resist and fight it.  
 One of the worst scams out there. I’d argue one’s genetic code is more valuable than their seed phrase. 

You pay them, they get massive amounts of data, which they always lose, and you get to find out you’re 1/16 Mongolian. Winning! 

Sigh… 
 Had some immediate family members do this, and get slightly different results.

It appears that some markers are attributed to one unusual heritage or another one based on your travel search history. 

Wish I was kidding.

Its all "the AI did it", of course, and dollars to doughnuts one of the AI's inputs is a data-broker's "ethnic affinity" assessment of your search history. Maybe literally Meta's "ethnic affinity" metric.

"Gee Sarah, you've always liked Korean pop music, and gosh it turns out you might be 1/16th Korean. Now a word from our sponsors..." 
 Right, there’s no real verifiability for the user. 
 But are you okay with your brother "sharing his DNA" with a random stranger that he met at a bar? 😆 I see no difference🥴 so what they can turn us into a GMO with this info. At least now you can tell people exactly how oppressed your bloodline is. For example I did that same test back in high school and I found out I'm 14% oppressed. Let my people go!  
 The problem isn't DNA collection. It's the indirect link created by gov records that links you to his DNA. 
 ...that and massive data breaches. Why are some people so willing to share everything? The mind boggles. 
 The cops can use your DNA to perform a genealogical search to find their suspect by linking them to familial DNA in the databases of these DNA services. If you submit your DNA for these cute evaluations, you're potentially ratting out family members who might be on the wrong side of the law.  
 The wrong side of the law, the wrong place at the wrong time, or just work in a lab with careless colleagues.

Good f--king luck explaining that one to a judge after the prosecutor has already spun a truthy little narrative to the court. 
 Or isolating yourself as genetically disposed to violence or.. ambition that makes you a "political risk". Seems like a great way to id yourself as a dissident.  
 Yes. Not to mention the data gleaned by health providers, it's just a terrible idea. But people seem not to realize how much data they are willingly bleeding out. 
 Not your keys not your dna sequence? 
 I disagree with this on a philosophical level. The info is theirs, they own it. Restricting this is copyright, and I don't recognize any forced copyright law as legitimate. 
 Of course, it is a very stupid decision. But like, several people removed from you, someone could still piece together information about your genetics. There is no way to enforce a ban on discovering your genes aside from people having the wherewithal to themselves opt for keeping that private. 
 Yeah I did this years ago with 23 and Me.  Now it looks like it’s a sinking ship and as someone else wrote, you’re never really sure if they actually destroyed your DNA or not.  However, I’m happy to report that I’m not 1/16th Mongolian.  😃 
 Entitled psychopath, stay the fuck away from me in real life
