Although the exact nature of the control mechanism may not be obvious, I can't see how the governing body would hand over any of the real direction of the WTBTS corporations.
Correct, they did not hand it over -- it was forced from them. Some of the GB are not at all happy about what happened either.
And yes, articles could come out that the GB don't want. After all, the GB is no longer in legal charge, and they no longer control the magazines. All it takes is for a disagreement to arise, and the GB can be cut out of the picture the same way Rutherford cut out the directors way back when. Irony, to say the least.
