Public Comments are Public, Awareness Is Private
"The process also received an enormous amount of attention, so it is going to be very hard for the states to argue persuasively that the public comment process that is designed to ensure that decisions are not made in secret is valid in this case."
There's a difference between a lot of attention and an official public comment period. An official comment period involves gathering public comments over an established period of time to be reviewed and taken into consideration by the office/department that is proposing the law/regulation/change in administrative practices etc. Just because you're aware of something doesn't mean you have the ability to directly comment to the decision makers.
