content: There is a filter that you have to opt out of if you want to receive certain types of materials, yes. It also blocks a whole host of legitimate sites, as well. It is really just them setting the stage for greater censorship. Honestly, this is happening all over the world right now, even in the United States. Many countries are slowly building the tools for mass censorship and even creating "off buttons" that either cut a nation off from the rest of the world, or just kill the internet entirely. One of the scariest I have heard of is information intercept and alteration, where a company, person, or government, could intercept packets coming from a certain site (like a news site), and alter what the receiving party sees without either party knowing that what is being read isn't the information as originally written but rather a "propaganda" version changed to fit the abusers narrative. It is so subtle that it is frightening.
