Out of all the major tech companies that you could “break up” doing that to Apple would probably make the least sense.

Integration between devices/software is their entire selling point.

Yes? That's a feature? I mean, nobody wants to break up companies in order to make the companies more effective or more profitable.

It's always done to end monopolies, to open up closed markets. The people benefiting are consumers and competitors, not Apple itself.

Well it’s not at all obvious how consumers would benefit from that.

If the deep integration between hardware, software and services is the main reason why people buy Apple’s products the harm from breaking the up might outweigh any of the benefits.
