How is that censorship? It's a private company, they should be free to choose what kind of content they want to provide.
Censorship is just a classification of what they are doing. In both cases, it is selectively application of blocking of contents based on one's political believes. Calling them censorship is not an assessment whether they have a legal/illegal/legit/reasonable/unreasonable cause to carry out such acts.
I just find this approach somewhat ironic.
