Fighting against a nuclear project in France
Robin is an activist in struggle against a nuclear project in France. He has been using Tails as his default operating system for all his activism since 5 years, creating a clear separation between his activism (using Tails) and personal life (using encrypted Debian).
At his place, many nomadic activists use Tails USB sticks instead of having personal computers, allowing them to maintain privacy while using shared devices.
After facing repression, encrypting all their data became a baseline practice in his group. He prefers training others on Tails because it's easier to implement than teaching full computer encryption.
Because Tails is easy to share, even people with low technical abilities are able to use it. For the security of a group, what matters is the lowest security level within that group.
