Citation needed. RMS, the FSF and many other orgs made public statements around privacy many times.
Now, I can't exhaustively prove a negative, but I think I can easily demonstrate that the FSF has never meaningfully expressed an opinion on privacy. Go to https://www.gnu.org/philosophy/philosophy.html, open every single page it links to in the body of the text, and search for the word "privacy". It does not show up in the body text of any of those documents. It shows up once in a footnote that mentions a change that Samsung made had that "caused privacy concerns".
The closest they get to even mentioning the concept of privacy is when they talk about the right to modify software and use those modifications "privately", which clearly does not mean anything about user privacy.
If privacy were so big of a concern for the FSF, you'd think they'd talk about it in their official documentation on their philosophy, or put something about it in the ONE tool they have to have power over anyone: the GPL.
