The specific journals you refer to in the wikipedia article have dropped in popularity, but this particular one hasn't. Frontiers is a huge family of journals. Some are good, some are excellent, some not so good. I wouldn't call any of them predatory though. And even if there was controversy in 2015, 7 years can be a very long time in publication contexts. One thing that is interesting about Frontiers is that they encourage open reviews (i.e. the review is public and accompanies the paper). This is pretty far from predatory journal behaviour.
