I think a key ingredient is translators that move content out of the platform-bubbles into the world you control. You can move material between RSS, email, blog channel easily, if you choose. Harder but doable is to crack the walled gardens of social media.
These can fuel development of better forms of expression than the primitive nonsense so often used today.
Many people have major barriers; not interested in taking control, not going to build anything myself, fear of leaving the mob, will accept advertising, want somebody to tell me what to do, too rushed...
That's fine, they will continue. Those who want can, and are, going down the other road.
