If you wanna define it like this then apple would need to be your home ISP too.

And owning all the fiber connections between the base stations and their network.

And all connections from home to their network.

And even if they have that, you are not browsing Verizon services but from others like Google etc.

They don't do that.

Closest operator I know could be German Telekom because they came out from the state owned Telekom company and they got all the copper which was laying around.

I am not sure how else to define "fully integrated end-to-end".

Http, https, etc. the protocols responsible for the end to end communication

Protocols and nodes are not the same.
