"Google is preventing competitors in the voice assistant market from reaching consumers through connected cars, which stand to be a significant way the internet is accessed in the near future," said Iowa Attorney General Tom Miller. In 1998, Miller was one of more than a dozen state attorneys general who sued Microsoft Corp, then the reigning tech giant.
The complaint also alleges that Google uses its SA360 software, which advertisers use to buy search ads and which is supposed to be neutral, in order to steer ads toward its own search engine and away from Microsoft's competing search engine Bing.
