One giant advertisement
How does a passage like this end up in a Featured Article? (my bolding):

"The company says that the accuracy of the test exceeds that of conventional methods, such as ultrasonography, amniocentesis, or chorionic villus sampling techniques, and that their test offers "unsurpassed accuracy, unrivaled earliness, and uncompromised promptness".[4] Acu-Gen has chosen not to release details of how the test works or proof of its accuracy"

So basically an unproven claim has been allowed to stand in a featured article - a claim that makes nice advertising for the company.
That this has been promoted to Featured Article status SUCKS. Now every company will get their PR people to write a nicely-worded, generally positive article for their products and Bingo! Millions of dollars worth of free advertising.  Shame on you, Wikipedia people.
