Antitrust orders are more complicated than just declaring a business unit spontaneously independent. They usually include provisions to ensure the the situation is actually fixed, like prohibitions on the parent competing in that entire market and financial/infrastructure support for the new companies on their transition to independence.

Are you able to share a case when an American court issued such a broad order on a F100 company? There was a stronger case for breaking up Microsoft, but the DoJ shied from that remedy, there was never a chance that Google could have been broken up in this case, IMO.
