Is there a platform that cannot be blocked by governments?

Iran is currently blocking off access to Instagram and Whatsapp and killing it's people: https://www.reuters.com/world/middle-east/iran-restricts-access-instagram-netblocks-2022-09-21/

If there is a way to allow people to access the internet, communicate, and overthrow such corrupt governments I'd love to dedicate the next chapter of my life to it. I know they also block internet access which is a tougher struggle I believe. Is there a solution?
