You are probably right that the article reveals some uncertainty wrt. the CentOS project as it currently is organized. And sure the delay in updates is far from ideal for certain users. Maybe this information is new to some users, but that doesn't mean it shouldn't be reported on.
But I don't think there is any strategy behind it, I'd prefer a more positive article myself about CentOS. But in the light of things I agree with the article. It's up to the project to improve what can be improved and clearly communicate what is inherent to the project. I prefer users can make an honest decision with all the facts laid out before them.
And that's what I tried to do with my CentOS presentations. It's not all good news. But that doesn't mean it is "FUD".
PS If it is unclear, I am "Dag Wieers" from the article
