For years #media and other orgs have been saying "we can't move away, our audience is there" whenever a prospect of maybe not supporting centralized services came up.
But that ignores the 1% Rule: "only 1% of the users of a website actively create new content, while the other 99% of the participants only lurk".
https://en.wikipedia.org/wiki/1%25_rule
In other words, audience follows those who create. If media orgs moved, audience would move with them. In other words, they had it all backwards.
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?
