At the end of the day, it's up to the S. Korean govt. or regulator to make the changes necessary to get rid of this nonsense. The govt./regulators have other issues to deal with so these S. Korean 'tech' companies get to make a mess of citizens' computers and privacy. It's been well over 2 decades of crappy S. Korean software like the keyloggers and whatnot and no end in sight.
If S. Korean citizens cared, they would force the politicians to do something and it would change. They don't, so it doesn't change.
