It's all about money
Unfortunately, "Government of the people, for the Corporations and by the Corporations shall not perish from the Earth."
Whoever has the money (corporations) gives our rulers those campaign contributions that get them elected. This will not change, and it doesn't really matter a whole lot which party is in power. Money talks, and the rest of us can either
1) Get angry enough to vote for someone else -- except the someone else will also be on same payroll, so don't expect much change
2) Complain a lot but do nothing
3) Start a revolution (but once the new government is in place, see #1)
In the long run, it's unlikely that there is anything the average person can do to help the situation. Possibly if everyone got mad enough to write their Congresscritter and complain about this vote, it might be stopped. For now. But then the FCC will still deep-six it. And before long, they will sneak the same damn thing through Congress. They always do.
Just remember, whenever you use any of our modern electronic media, THEY are listening and taking notes, "they" being NSA/GCHQ (or whatever flavor exists in your country), your ISP or phone carrier and anyone they feel like selling/sharing everything you say or do with. There is no privacy with electronic media. None. If you want to communicate privately with someone, go into a room with them and make sure there are no electronic gadgets there. (And if you're real paranoid, remember, even windows can be a problem.) Otherwise, whenever you converse with anyone, assume THEY are listening, because they pretty much are. You can try using ProtonMail or something, but eventually the governments will either backdoor it or outlaw it, so we'll all be back to square one.
