The same argument you're using is an argument used for spying and throttling/capping of internet connections. It's an attempt to get us to turn on each other instead of the corporations screwing us over. Don't take the bait.
I find myself far less likely to vote for national candidates that send direct mail. More-local candidates that send direct mail make more sense, since I wouldn't likely know their positions otherwise.
Cases in point:
I get junk mail from "Romney For President" because I'm registered Republican. I would never vote for him for president (though I voted in the primary). They're wasting their money. They even ask you to put your own postage on donation envelopes so they don't have to pay it. That's led me to consider sending it back empty.
My girlfriend gets junk mail from "Obama For President" because she's registered Democrat. All the direct mail they send her talks up his Obamacare and Immigration policies, the two things she most dislikes that he's done. The junk mail has almost let me convince her to vote third-party in the election.
I don't think these political groups know what they're doing as much as they think.
Once again: seeking to stifle speech online is only likely to give that speech much, much, much more attention.
We really don't have any idea how often the censorship is effective; we generally only hear about the cases where it's successfully protested. I would presume that it's effective a lot of the time, or else the "reputation management" companies that do it would be completely out of business.
That probably isn't on the list because their "broad range of political backgrounds" economists don't agree on it. The things on this list are things that shouldn't be controversial. Our level of military intervention in the rest of the world has always been controversial.
"The new Linksys EA4500, EA3500, and EA2700 routers are available now and cost $199, $139, and $99, respectively. Cisco promises that a full range of its cloud-enabled services will be available by June."
This was actually an on-the-box feature, from what I've read, that these routers would receive a free upgrade to the new "Cloud Connect" firmware when it was available. So it seems right that they would receive it.
For someone who understands the meanings of the terms but isn't familiar with the US parties, "Democrat" and "Republican" parties could also be confusing. But names are often just names, and people tend to figure these things out.
