Are there any famous celebrities that advocate Free Software?

Thesci-fi author, Cory Doctorow comes to mind. He addressed this spring's Libreplanet conference and was a hit!

There are so many, please forgive me if I forget some names. Besides,
this list is in alphabetic order, and I also inserted those beyond
famous, because I don't want to keep giving credit only to specific
already known "stars".

- Adonay "adfeno" Felipe Nogueira (it's me, ;D), member of LibrePlanet
Brasil;

- Allison Randal, from FSF;

- Alexandre "lxoliva" Oliva, from FSFLA;

- Anahuac de Paula Gil, Brazilian famous for giving very useful talks
that provoque people on questioning what they know about Tux, Linux,
and open source, where in the end he always mentions and favors
free/libre software philosophy;

- Benjamin Mako Hill, from FSF(?);

- Bradley "bkuhn" Kuhn, from Software Freedom Conservancy;

- Christian Grothoff, talks about GNUnet and GNU Taler and mentions the
free/libre software philosophy in these talks;

- Christopher Allan Webber, developer and writer of some federation
standards that are currently in the making;

- Karen Sandler, from Software Freedom Conservancy;

- Katharina Nocun, politician which also gave a talk during Chaos
Communication Congress 32c3 (2015) in favor of free/libre software,
federated social networks and communications and also on distributed
ones;

- Larissa Oliva, Brazilian who gives talks on the importance of
free/libre software and education, although I don't know if she gave
talks on the importance of the philosophy. Anyways, seeing younger
people getting interested in this area never stops amazing me;

- Luis Villa, a lawyer and former developer;

- Marianne Corvellec. She gave a talk on LibrePlanet 2017 providing an
alternative view of the ethics (or lack of) in free/libre software
movement and in open source development methodology;

he describes the difference between Secure Boot and Restricted Boot;

- Nelson de Luca Pretto, Brazilian who does research and talks
describing the importance of free/libre software philosophy to
education (if and when the education is to be made with computers);

- Shauna Gordon-McKeon, gives speeches on democracy, artificial scarcity
and free/libre software. As far as I remember, she gave talks both in
LibrePlanet 2016 and 2017;

- Sva, talks about GNU Taler and mentions the free/libre software
philosophy in these talks;

- Thadeu Lima de Souza Cascardo, Brazilian who gives talks about the
importance of copyleft, community-oriented enforcement and free/libre
software;

I have listed some speakers that I remember just now, not users.

Once again, forgive me if I forget one. ;)

All of those are preachers to the choir. What I think the op is after are names of of celebrities who are known more for their work outside the free software connunity, but who are allies. Hence my mentioning a well-known SF author. On a related topic, who has seen product placement of a GNU/Linux distro in pop culture? Once, so far, I heard the name Ubuntu in a massively-popular sit-com.

Btw I use and advocate, I'm famous in my town.
