Men like Romney are also looking at companies with the possible goal of breaking them up and selling different divisions off. To do this they must know if there is anything objectionable or problematic.
This is no different than what happened with Apartheid back in the 80s. Just about every major corporation had to go through every aspect of their business and divest themselves of anything related to South Africa. And they weren't doing this because they had to, they were doing this because the public and their shareholders demanded it.
Absolutely.
Romney knew full well exactly what he was profiting from. The chances that he didn’t are ZERO.
