I spent several days working on my comment; it was a dozen pages long, it included relevant citations, and it addressed specific questions asked in the NPRM. I took the time to correct a few falsehoods in the NPRM's technical analysis.
Now imagine what it is like to see that comment being specifically cited and totally dismissed in the draft rules that were just approved. In a way it is worse than just being ignored -- someone took the time to read my comment and comments by like-minded experts, saw the part where we corrected falsehoods, and then replied with, "Well, ISPs say $X so $X is true and your comment wrong."
I am not going to give up on civic engagement but I am sure some of those like-minded engineers and researchers might.
