they spend far more of your subscription PCM on VM core network bandwidth passing over the external links, were an internal re-config would more likely push it over the available direct peered links in the data centers around the world.

I spent a little while contemplating how to answer this but will settle at saying that Google has denied you information here and that must be your only source given that anyone who has worked with broadband networks knows where the costs are beyond any doubt.
It's not a 'one off' cost when an operator has to spend 6k on lasers, at least another couple of k on engineering time and possibly tens of thousands more pulling fibres and doing civil engineering just to deliver another 50Mbps to 500 customers when the bandwidth fills up.
The CMTS cards themselves are still a bucket load of money per downstream and remembering how few customers each card serves that takes a while to get back.
As a thought to you for the price of the lasers just to do a single HFC node split one can purchase 2 x 10Gbit Ethernet extended reach XFPs.
The HFC network is, bar far, the most likely section of network to experience outages due to it being out in the field with no resiliency as you'd find in an optical backbone ring.
VM budget their customers at around 100kbps each - cost to VM even if zero peering is used on this at core level is going to be less than 50p/month even worst case. An average optical resegmentation affecting 500 homes and costing about 10k will take over 3 years to be paid for at that price.
Think economies of scale - you run on the core network you're one of many running on nice big links in big fibre bundles with off the shelf equipment as found in core networks everywhere going off to connect to other ISPs at high volume pre-negotiated rates. When you're on the cable network you're sitting on your little 500 - 1000 homes passed fibre optic node having a service delivered via ruggedised equipment in street cabinets. and soaking up half of a CMTS line card that costs as much as a 10GbE ER XFP, along with an optical transceiver system that costs as much as a pair of them.
I have as you may remember worked for both the 'cable company' and a 'DSL company' and can assure you that in both fields the investment in the core networks was nothing compared with node splits and plant upgrades on the cable side and exchange backhauls and MSAN installs on the DSL side.

Yes and yes, they've done considerably more than 10 in the past.
