Join the Global Climate Strike 20-27 September
Climate activists around the world are demanding action on climate change
You're right, activists would benefit from safer tools that are easier to use.
I'm not sure that the number of Tor relays in a country matters that much for anonymity. But the number of Tor users has a big impact. That's why we train people to use Tor.
I don't think Tor should get involved in mainstream political issues, other than things which directly affect Tor Browser such as privacy, surveillance, and net neutrality. Tor Browser getting involved in mainstream political issues like abortion, climate change, war, health care, etc. will only alienate people.
