> This initial ruling establishes the precedent that the FCC has regulatory authority over the Internet.
No, it doesn't, its not the first FCC regulation directed at the internet. Its one of several assertions of FCC regulatory authority over aspects of the internet.
Further, even if it did establish that precedent, it still wouldn't do anything to affect the capacity for future bad regulation, because any future regulation could do everything this did plus any bad things all at once, there is no need for separate and preceding "precedent" creating action by a regulatory body to enable future regulations.
