It's all the same scam - you send them your dna to do some fun test, like see what % of neanderthals genes you have or how much Scottish you are (which is btw a total scam because error margins on these tests are usually huge and thus results are pretty meaningless) and your dna ends up in their database forever, and they can data-mine and cross-analyze and sell it as they wish. Of course they have good lawyers and EULAs and it's all legally covered, but it's just as immoral.
