As mentioned in the article, this requires a DOCSIS 3.0+ modem, and there are costs to rolling out equipment. Cranking up the speed isn't simply a matter of turning the dial on their end.
However you are correct that coaxial cable has plenty of room for improvement with a cost that pales in comparison to rolling out FTTH.

tl;dr: by using more spectrum in the coax cable can get pretty fast... So pressure from Google should get them to crank up the speed sooner than later.
