Silly and retributory, and per the article a pretty clear violation of Washington State's net neutrality laws. But in context, probably not a bad thing for society.
I also disagree with what the other companies did in the first place is censoring. They're removing rule breakers. You can still share your political views, just don't organize and call for the government to be other thrown because you believe everything you read online. You wouldn't freak out because a child porn distribution platform was turned off and claim it's censored.
They don’t regulate transmission because that is federal territory.
Now the article is slightly misleading because they didn’t block Twitter and Facebook globally. They only blocked traffic for those users that asked them to do so.
Washington's net neutrality law covers home service.[1]
