It takes time to uncover that Microsoft had done something tax worthy without telling anyone. Microsoft bought a danish company, then sold a huge asset from that company to another Microsoft owned company in Ireland (probably for tax reasons) then told the danish tax department that the asset was worth less than it should have been, thus avoiding large taxes. This all takes a while to uncover, then it has to be double checked. Then you have to talk to Microsoft about it....and then you can tell the press about it.
