I don&#x27;t like this sentence from the wikipedia page [1]:<p>&gt; The price of the full direct to consumer testing service in the United States has reduced from $999 in 2007 to $99 in 2012, and it is effectively being sold <i>as a loss leader</i> in order to <i>build a valuable customer database</i>.<p>First, why can&#x27;t companies these days just sell me a product for the cost price plus a margin? This seems like a fair way of doing business.<p>Second, what do they want to do with my data? Why do they think it is valuable (will they sell it)? Why can&#x27;t I just get my data without them keeping a copy of it?<p>(It isn&#x27;t because they offer an online comparison&#x2F;discovery tool, since they could easily offer that as a downloadable app, so they don&#x27;t need my data on their servers; it also isn&#x27;t because they need to do research on the data, i.e., to find correlations, because they could make that voluntary).<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;23andMe" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;23andMe</a>
