Honestly, I don't have a problem with the article itself, though some of the comments are...well, let's just say they're exactly what I've come to expect.
Throughout the article the authors are very careful to say again and again that no one should stop breastfeeding. That it is the proper thing to do.
A couple of the commenters, I think, get to the heart of the matter. There are two huge things going on: Mamas who want to breastfeed now probably weren't breastfed as children, and so their own mamas cannot help; and there is a lot of piss poor advice being given out, much of it by healthcare workers who really ought to know better. We have the exact same issues in the US, and if articles/studies like this lead to better training, then all the better. It's horribly necessary. I can't say how it is in the UK, but when I had my first two daughters, my postpartum nurses were almost uniformly clueless about breastfeeding (I got lucky enough to have one who had somewhat of a clue).
Yes, some people will take this article as an excuse to say "See, formula's not that bad" (as, well, they have), but those are the same folks who have that as their battle cry anyway.
