Misleading title. It's a solicitation for entries to a contest (the Open Technology Fund) that awards money to disruptive technology projects for advancing Internet freedom and human rights.
The contest is being administered by an organization (Radio Free Asia) that has been criticized as propagandistic in its charter to provide information to people in Asia who lack adequate protections for freedom of expression, free speech, and a free press. See: https://en.wikipedia.org/wiki/Radio_Free_Asia#Criticism
I have no idea how they derived that title from the email.
I also object to the use of the word "propaganda". In fact, ironically enough, I think that singling out US propaganda is itself kind of propaganda. I have little love for the USA but be fair: to reach out to the types of people who'd be listening to "Radio Free Asia" you need to fight fire with fire.
