I am pretty sure there is nobody anywhere at any Sony subsidiary who had anything to do with Sony Music and SCE decisions in question simultaneously. As same as there is nobody in Berkshire Hathaway who is simultaneously deciding on the candy recipies and on the insurance policies.

And I don't think that lobbying efforts are undertaken without the involvement of senior management (unlike, say, candy recipes), so we'll have to disagree here.

Pardon my ignorance, but in what world installing a rootkit is a part of lobbying efforts?
