Does this mean that the FCC's Net neutrality rules don't apply to any broadband provider?

The court's decision applies to all Internet and broadband service providers, except for one: Comcast. As part of conditions it agreed to when it purchased NBCUniversal, Comcast said it would abide by the FCC's Open Internet rules for seven years, even if the rules were modified by the courts.

"Comcast has consistently supported the Commission's Open Internet Order as an appropriate balance of protection of consumer interests while not interfering with companies' network management and engineering decisions," Comcast's executive vice president, David Cohen, said in a statement. "We remain comfortable with that commitment because we have not -- and will not -- block our customers' ability to access lawful Internet content, applications, or services. Comcast's customers want an open and vibrant Internet, and we are absolutely committed to deliver that experience."
Cohen went on to say that his company plans to work with FCC Chairman Wheeler and the rest of the FCC to find "an appropriate regulatory balance going forward that will continue to allow the Internet to flourish
