Reasons not to reveal your DNA
The danger about making these lists is that you may end up thinking that you have to get a high number of reasons to make your claim seem valid. I would not be surprised if the author started stating five to ten reasons and then thought that 23 was a good number for the reference, therefore proceeding to fill up the article with whatever nonsense. That's the only process I can think of that nets you "they sell your DNA to other companies", "scientists can make gifs with your DNA" and "companies buy ads" to be arguments in the same hierarchical level.Some of them are pretty serious consequences of using their services: some of them involving the company's practices, and others involving the dangers of developing this industry. Both should be considered in separate to get a clearer picture of the issue. This article is treating it as BuzzFeed treats a new game of thrones episode, therefore depriving it of any legitimacy.I'd like to see more elaborated on three points particularly: the privacy implications of having your DNA shared, the accuracy and precision of the purported results and the possible dangers of applications of this industry.
