Google has come under yet more fire regarding its anti-trust measures, this time in South Korea. As a similar legal case with EU officials hots up, the American company has now had its Seoul headquarters investigated by the country's anti-trust regulators, concerning alleged anti-competitive behaviour regarding its Android operating system. The Korea Fair Trade Commission inspected the offices in the capital last week, after the EU filed its own complaints over the same matter; i.e. the fact that Google made it impossible for smartphone producers who used Android to sell another operating system. This also comes just three years after the company was cleared over anti-competition claims built on the fact that smartphone makers using Android were forced to build the search engine into the devices.
