The founder died as this was happening, and I was quickly warned by some decent insiders that I should cease all contact with my benefactor and get away ASAP. The sons of the founder were going to fight for power and, as the Koreans say, "when whales fight, the shrimp's back gets broken". In a clash between the most powerful men in a military dictatorship, little people could have tragic "accidents", and so what? I took their advice.
The same family controls that company today. The guy just arrested is the nephew of my old "benefactor". The country is no longer a dictatorship, but the powerful people at the top haven't necessarily changed their ways. Every few years, there are accusations that the top Samsung people are guilty of bribery or similar manipulations. Hard to believe, right? They'll get charged, then the charges are dropped. They'll be convicted, then pardoned by the President. These are power struggles by people who are all above the law but not necessarily above one another. If you do business with them at the small, overseas, trivial level, this may not matter, but you should be aware that behind them you have a system that plays by older rules.
