I don't know your motivation, but your remarks do not match my reading of the article. The dismissed studies came from children in unrepresentative conditions (ignoring the fact that this kind of data is extremely noisy and that studies in social sciences are notoriously bad).
It's also not "both-sides-ism." The main anti-daycare fear mongering seems to center around the idea that it's bad for your children, but the opposite is suggested by the article.
Sorry you wasted minutes.
