To the downvoters, I'm curious why you think America weakening its largest tech companies wouldn't help China? The fact that people are calling for breaking up large tech companies suggests they have an unfair advantage over small companies (otherwise they wouldn't need to be broken up), so why wouldn't large Chinese tech companies have an advantage over small, broken up American companies?
