MSNBC isn't an "art company?"  What do they produce?

Yes, they're owned by GE.  But then the question to be asked is how much GE micromanages MSNBC.

As for George Soros, um... he REALLY doesn't count here.  He's not a business manager.  He's an investor.  That means:
A: He's not an organization.  Nobody has to check what he says.  If he wants to invest in GE, damn it, he will!  If he wants ice cream for breakfast, he gets it!
B: His profits aren't extremely rooted in politics.  Yes, changing political climates will change investment potential.  But even in the worst of depressions, investment potentials exist. 
C: His assets are liquid.  Even if Congress started setting up regulations on investment profits of some sort, at worst, Soros could just take a small chunk of his money and leave.  The biggest expense would be the plane ticket out.
