This is actually startlingly true.
replyEvery FAANG company has their own fiber backbone. Why invest the internet that everyone uses when you can invest in your own private internet and then sell that instead?
It's not like the long-haul fiber not owned by FAANG is a public utility, at least not in most places.
replyTraffic that goes over "the Internet" traverses some mix of your ISP's fiber, fiber belonging to some other ISP they have a deal with, then fiber belong to some ISP they have a deal with, etc.
All those ISPs are being paid to provide service, they can invest in their own networks.
And we all know that ISPs are famous for investing in timely infrastructure upgrades.
