I've been volunteering teaching Latin American journalists how to research, communicate, and store data privately to protect themselves and their sources against attackers. The threat against freedom of expression there is just as real as it is with oppressive regimes in other parts of the world although they don't get nearly as much attention as the Middle East. This article doesn't highlight enough the need for volunteers and professionals to lend a hand. Most recently I've been working with journalists in Venezuela. If you know anything about Venezuela you should know that they have an incredibly oppressive government and they also have had massive inflation further eliminating their buying power. Things like a $3 (USD) a month VPN are hard for a middle class citizen to afford.

I'm trying to remember where I saw it, but there was a journalist who showed over the past year how much food 1000 bolivars bought. At the beginning of the photo essay, she could have fed a family for a week. By the end, it was barely enough for 1 person for a meal.

Anyone can really help out and make a difference too. Not just in LATAM, but around the world. The amount of knowledge about cybersecurity, threat models, and risks associated with electronic communications spans a wide range. Of course you have civil society groups who know how to use PGP, but there are others who still rely on Facebook Messenger to communicate with sources and keep passwords sticky noted to their computer screen.

Edit: Also wanted to note that it's pretty great what Citizen Labs is doing. Other great resources for learning/teaching/staying updated ( in both English and Spanish and several others) can be found on the EFF's website - https://ssd.eff.org/en/playlist/journalist-move
