The fundamental problem with pitching a technology as one that helps people fight for their rights is that such technology is banned by the oppressing regime very soon.
However, there have been a lot of cases where apps (with different main use cases) have been used by oppressed communities to communicate. Two apps immediately come to mind:
1) Firechat: Hong Kong protesters used this app to communicate with each other without being intercepted by authorities.
2) Threema: An app which provides end to end encryption of messages is serving as a life-saver for the LGBT community in Lebanon and Iran where the punishment for being gay is death.
