That's not going to happen with the way tech/algos are exacerbating the divide.
We need to be proliferating alternative, humanistic, empathetic software in the world and putting it into people's hands. It's easier than ever for us to independently build a wealth of defensive infrastructure for the common people.
We have to use our intelligence and expertise to make applications which take care of users and their privacy, without them needing to suddenly become overnight computer experts. Most of the tooling I see today has (understandably) massive UX issues and is largely relegated to at least the mildly technical.
We need new and open Facebooks, TikToks, calendars, operating systems, etc. which protect and empower people but don't complicate their lives and stress them out, which leads to security and privacy fatigue. Even my current operating system, macOS, is so intensely user-hostile and obfuscated off the happy path, despite being heralded as a champion of human-oriented design.
We need a modern GNU-like organization but focused on building the social/web tooling that most people today are using.
Most people don't care enough to even ask the questions. Creating competing services were the value differentiation is privacy (likely at the trade off of cost or quality) is bound to fail for that same reason.
