Korea is a major world player with aspirations to dominate the world economy. That’s kind of the premise behind capitalism. Samsung isn’t content being a small company, they are a megacorporation involved in pretty much every part of Korean society, from heavy machinery, to insurance, to medicine, electronics, capital investments, construction and more. Your assertion that only china wants to dominate international markets is patently untrue. Capitalism is defined by endless greed. No corporation would turn down domination if it has the means.

Corporations are not democratic. Korean citizens do not get to vote for the samsung president. Corporations are the ones doing these things, not democratic institutions.

Security and privacy are issues that matter. Violating privacy and making devices less secure isn’t only a problem when china does it.
