I don't know whether Karlin was directly involved in the Human Genome project, but most major centers for genome research were involved in the Consortium effort. It's a very public shouting match, about what you would expect among children on a playground, but with fancier toys and written down in the best scientific journals. Probably most, but not all, of the criticisms have merit. That's just a guess, since I don't know enough about the specific claims to be a decent judge. I think the criticisms have merit because this is how science usually progresses.
Someone does an experiment, they report the results, draw some conclusions.
The more data you have, and the more time you have to figure it out, the more likely you are to arrive at something like the truth. The Celera scientists want to win. They want to win so that they can get rich. They want to win to be the winner, just like children racing, or arm wrestling. The motivations of the consortium scientists are a bit different, but no less complex.
