Public comment is explicitly intended to guide policy. It’s not a vote but the entire point of the process is to get feedback before a policy is finalized and most agencies attempt to address common points.
It’s reasonable to question the inherent assumption of good faith with the current administration but we’re also in an unusual time where the most cynical view of previous administrations are now the smart money view of how things work.
In this case, having tons of AstroTurf comments allows them to say that there’s public support outside of large ISPs. Given how anticompetitive the decision was, they needed that fig leaf.
I suspect this incident demonstrates the scope of disinformation campaigns and the industry that enables them.
It is totally possible that cramming a couple million fake comments into the FCC was done solely for the purpose providing a politician a "talking point" in favor of getting rid of net neutrality.
These fake "grassroots" operatives merely abused the web-commentary system in order to keep the FCC leadership (and Republicans) from being completely humiliated by the sheer number of people in favor of net neutrality. Turns out, they got sloppy and went a bit overboard.
What is really disturbing, however, is that the company named, "CQ" is in the business of automating "campaigns" with software and data analysis. To them, it doesn't matter WHAT the campaign actually is as long as they get a paying customer-- smears and disinformation is just another day of work for them.
There's so many layers of slime here, it's hard to know where to start.
