Read the same article and I love this paragraph:
...On the other hand, moving to the customer-owned model has benefits for the cable company. Time Warner isnt rolling trucks out to make the switch or install new modems for customers, for example. Tech support could also be sloughed off on the cable modem manufacturers. And once youve bought a modem that only works with Time Warner, youre less likely to switch to a competing service.
1) Not many people have a choice and cannot switch to another provider even if they hate their current cable provider.
2) DOCSIS is a standard. A DOCSIS modem should work on most any cable system.
3) The cable modem manufacturer is going to support your Internet connection when HSI isn't working? Really? I've had DOCSIS-based HSI from Charter since August of 2000. For the better part of a decade, I used one of the 3COM "Sharkfin" DOCSIS 1.1 modems. When my HSI didn't work, it was never the modem. For the past several years I've been running a Moto SB51xx DOCSIS 2.0 modem and likewise, when HSI hasn't worked, it's never been the modem. Sloughing support off on the cable modem manufacturer sounds like a pipe dream.
