These are companies that respond to market pressures. Routing around the network operators (both figuratively and literally) makes a lot of sense for large cloud providers. Especially so if there are no network neutrality rules in place to enforce free access to consumers (as opposed to consumer ISPs demanding payment for pushing content to their subscribers).
Also, the content from Google, Facebook and a couple other cloud providers is what consumers actually want. I've seen internal numbers from a European mobile provider that show that >80% of consumer traffic is to/from either Facebook or Youtube. So are the consumers villains?
If you measured that by doing a count() and group by on the domains of a traffic log, it would be easy to draw a conclusion that doesn't meaningfully reflect real user activity.
What content from Google and Facebook? If you are referring to YouTube and Instagram - that's one part of the total internet content consumed. Hard to totally ignore the news sites, blogs and streaming services.
The centralization of the internet and death of the “end to end” ethos is very real unfortunately.
They aren't a villain, they're an illustration of market forces currently favoring centralization. Like CenturyLink and Comcast, for that matter.
You statement is the exact opposite of reality.
