Finding the information can be easy, but coming to a conclusion from it is harder. For example, in the links you provided, we can see that AccessNow is supported by Google and Facebook, but also by Mozilla, which is generally considered to be a strong privacy advocate. Similarly, CDT is supported by Google and Facebook, but also by DuckDuckGo and Mozilla. So what can we conclude from this? I'm not really sure. It could be any of: 1. Mozilla, DuckDuckGo, etc. are supporting organizations that are working against the interests of privacy. 2. Google and Facebook actually care about privacy. 3. Privacy is a complicated issue and there aren't really well-defined "sides" to take.
