How does their action of removing these apps square with this human rights policy document? Did they give themselves a loophole to make it okay, or are they just blatantly ignoring their own publicly stated values?
There's nothing in that document (if you bother to read it) that says "We will violate the law if we don't agree with it." In fact it states:
We’re required to comply with local laws, and at times there are complex issues about which we may disagree with governments and other stakeholders on the right path forward. With dialogue, and a belief in the power of engagement, we try to find the solution that best serves our users—their privacy, their ability to express themselves, and their access to reliable information and helpful technology.
