Yes, individuals can flee to get out of the path of said shit snowball, but their descendants, family, friends, and neighbors are directly down hill from it.
I'm not too optimistic that its possible to have enough people willingly boycott these news delivery pipelines to the point where it changes the ad dollar calculus for these corporations. They have been pretty great at cultivating addiction in a large proportion of the population, it seems like an extremely tough battle.
Do you mean all people? Or a small portion of those people? Maybe building a shit snowball bomb shelter aka cutting internet to a household might be able to save a small portion of those people, but I'm not sure how anyone outside of elected representatives could ever hope to stop it for the wider population when the thing has so incredibly much inertia.
