А васька слушает да ест
There is an excellent extra Fable in Krylov's retelling of Lafontaine's/Aesop's fables in Russian.
It is the fable about the Cook and the Cat. The Cook catches the cat in the act of stealing a big slice of ham and starts to chastize it. You bad kitty, yadda, yadda, yadda. And the cat listens and continues eating (А Васька слушает, да ест).
There is no baseball bat here. The kittie will CONTINUE EATING until all SOHO routers by default come with blacklist/whitelist for UPNP firewall traversal based on MAC. Not in an approved list of people who update their firmware - sorry no NAT traversal for you so no access from the Internet, bad kittie, bad kittie - no ham for you.
The issue is that these erstwhile "giants" are not even in possession of a bat to threaten anyone with. They divested from most of their Broadband CPE business and for the little they still make (Cisco Cable) the software is NOT WRITTEN IN HOUSE. So there is no bat (except just Google which has the staggering CPE share of <0.0001%). So Vaska can continue eating while the cook can continue to chastize. Nothing happened here. Move along. These are not the "broadband giants" you have been looking for.
