Aren't there companies that provide the "caching server for free" as a service?

If I understand the author right, the big companies are allowed to set up caching servers at ISPs.

Isn't this basically a CDN? If you spin up your own screaming start-up you would first go with akamai or whatever and if you reach sufficient scale you set up your own agreements with ISPs.

Is the blog basically arguing for making it illegal to cut out the middle man here?

Most providers who do cheap/free CDN have exclusions for serving video because the economics of it suck.
