"What I have to say about the #TwitterFiles is vital for everyone to know to maintain our free society, but instead of writing an article or doing a podcast, I will post an endless series of tweets or explain it behind a paywall."
These people do not understand the internet.
They understand publishing, though, where there are bills to pay and agreements to be made for access to proprietary information.
So they agreed, reasonably, to let a certain outlet have the scoop, and others could pick up the story and run with it from there.
There's nothing particularly odd or unusual about that.
It's nice to think that someday that might happen, but that's not the world we live in this year, and so TwitterFiles scoops were released as per the present norms.
Arguably it was more important to provide that transparency today than sit on it indefinitely waiting for the new world of publishing to be built.
