Is this a serious question? Advertisers don’t know that you carry a gene that means you may prematurely die? They’d like to know though, so they can feed you life insurance scams when they know you’re vulnerable, “last chance” style round the world cruises, last will and testament legal services and of course pharmaceuticals. They also want to target your loved ones while they know they’re especially vulnerable after you’ve loss. They want to send your spouse widows dating apps and psychic hotlines, etc. Advertising is knowing your specific weaknesses/vulnerabilities and exposing you to your triggers in your most vulnerable moments,for profit.

Also, this data is correct, and it’s Data that can/will be used to deny people health coverage/insurance/jobs in the future. Also a potential tool to reveal layers of ethnic heritage they would make the nazis drool (look into how IBM did a version of this for the nazis to use the census to help enable the historic scale of that genocide). With trump potentially around the corner and other rising fascist powers worldwide, and the only way trump stays out of jail is to remain president indefinitely and “silence” his detractors, it’s just too much sensitive data to be amassed, especially by a poorly regulated private company. Also makes your DNA vulnerable to cups gaining access eventually and bringing you in as suspect for crimes you didn’t commit and, especially in places like Texas, executing you.

Better question is, why are you on the side of this topic that you’re on?
