How Do We Escape Computer Controlled Propaganda Flow

Many of us have ways to make the world right, but so long as our actions can be predicted, it doesn't seem easy to pursue them, and pursuing them may have consequences. This situation is well understood by something or someone, however. That's demonstrable in the prediction. It looks to me like we have at least 2 or 3 layers of this propaganda flow control, some new, some old. Huge world impacts by people who don't believe peace is possible, and have acted on that immensely. Does anyone have advice on what software developers can do during this time, to help the situation? Personally, I have no idea how to communicate with people who refuse to harm anyone, to work on solutions with them.
