No surprises here. US ISPs and cable companies (among many other industries) continue to rock record profits, and instead of investing, just buy back their stock, or sit on the cash.
On the technology front, this means that instead of upgrading backbones, or delivering native IPv6, or a higher quality of service, they are deploying stopgap measures. Some examples of this are Carrier Grade NAT (CGN) instead of native IPv6. “Dumb” DVRs that are less programmable, and less usable than some home grown solutions. No investment in technical support. Man-in-the-middle ad networks, DNS hijacking, abusive legislation, and other interference with their customers’ data.
As long as the last mile is a de-facto monopoly, that’s just what we’re stuck with.
