The private companies would very much like to allow them, as they pay their bills and are a big customer. They are choosing not to allow them because they are being strong armed by a part of the political establishment that considers the spread of the information this websites want to share as dangerous for the country or its citizens.
So yeah, there's some government action against this domestic terrorists and it's resulting in private companies banning their websites.
You can agree with the action or not, I think it's a good idea to have infrastructure in place that thwarts the spread of dangerous misinformation, but that shouldn't be censorship. It should be easy to access education and mental healthcare to help people be strong against misinformation on their own and without the long arm of the law having to babysit them.
