I remember the FCC passing hugely unpopular media conglomeration laws… and here they remain, after an overwhelming majority of folks were against it. Unpopular decisions are the norm for the FCC.
They are presidential appointees… and don’t care about votes, or you and me. Historically. They do seem to love big business however. They have no transparency either. I’m not sure how you gain leverage over those people, but I seriously doubt a million phonecalls, emails, and letters would do anything.
