By many people, yes. And here in Europe, it's even so much worse (right to be forgotten, all kinds of hate speech, etc.)

Yes. It is not political censorship, however. There's a spectrum of speech, and political speech is generally considered to be the most important kind when it comes to freedom of speech protections.

To expand on the thought: some Google results in the USA are removed because they're child pornography, and even viewing or storing images of such outside of very narrow contexts is a crime.

No. Much like trespassing isn't censorship either.
