It's not just about fedi, and not an either-or.
There are newsletters. There is RSS. Media orgs could choose to keep some presence on :birdsite: and other walled gardens, but use it to funnel people to channels under their own control — instead of the other way around, which is what they've been doing for years.
Instead of "like us on FB" on their sites, how about "Follow our RSS" on their FB profile?
Many of us had been making these points for years. Media orgs did not listen. Will they now?
And yes, I do believe media orgs bear *some* responsibility for and culpability in this crisis (for it is a crisis).
A decade-long unabashed and often uncritical promotion of centralized services helped to entrench these services as online spaces for public debate. Now we're all paying the price.
