As with most things in the software development world there is not black and white. There are cases where an anemic domain model is the perfect fit.
BUT there are a lot of cases where developers try to build a domain model, aka do DDD, and end up with an anemic domain mode instead. I think in this case the anemic domain model is considered an anti-patern.
Just make sure you use the best tool for the job and if it works for you don't bother changing it.
