I am curious if such thing happened, how would Chrome sustain itself as a company. I imagine Google would pay a hefty contract to it and keep their control, or some other actor would do and change the actors in the problem, but keeping it.
Fortunately, they chickened out when they realized that forcing Google to divest Chrome would result in Chrome being owned by Perplexity (an Indian AI company). Or perhaps somebody even worse, like Elon Musk.
