Important to note that the initial paper is not even out yet. It is supposed to be a foundation paper that does not focus on dinosaurs. It doesn't seem like this Twitter thread shows any true holes and I don't think the poster is a researcher.
The writer of the twitter thread is Brian Switek, who has written several books on dinosaurs. You can do your own search based on his name to see his credentials.
In any case, Neil Shubin, the discoverer of Tiktaalik, has posted this comment [1], in which he takes issue with the way the New Yorker article broke an embargo.
