Of course not. Not just because they are foreign investors who have no previous sentiment to the club, but largely because Bill was seen to save the club from demise in desperate times when he bought it. If the investors now invested back then, they would be given a lot of grace.
Of course bill being a blue helped, but i dont think it was the main reason for his easy ride thus far. The situation in which he obtained the club along with his ability to spit some carefully worded BS was the main reason.
