Comcast started doing this (they call it "Domain Helper"). It looks they've at least made some effort to make it less evil than, say, Verisign's "Site Finder" from a few years back. It seems to only intercept NXDOMAIN where the hostname is www.*, and they offer a way to opt out at https://dns-opt-out.comcast.net/ https://dns-opt-out.comcast.net/ .
