I haven't watched this programme, and I probably won't. So obviously, I can't comment on the programme itself.
personally, I had good feeding experiences and was lucky in that respect, because I know that many mothers don't, and they could be helped much more, by better breastfeeding support and more accurate information. At the same time, I think that mothers for whom BF could never work out even despite whatever support we could give them - or indeed, who didn't want to BF - are being failed on a massive scale.
As well as BFing my own babies, I did voluntary BF support. I did enjoy being there for mums and babies and trying to help them. However my impression was that there is misinformation out there in the BF advocacy and promotion communities. I have a science background and am well able to find and understand the studies which underpin the evidence base for BF promotion, as well as the studies (such as they are) informing the clinical management of lactation.
My feeling is that on both counts mothers are being given inaccurate information that in some, extreme, cases amounts to demonisation - for example in my experience of doing bf support it was common for support workers to talk about the "risks of formula" and to claim that "just one bottle can damage the baby's gut". It is also sometimes claimed that virtually all mothers can make enough milk for the baby to ebf - there is no study from a country like the UK which shows this is true. At the same time the "list" of outcomes that are benefitted by BF (as compared with formula) that is conveyed to mothers is often out of step with what is scientifically proven - the degree of confounding in feeding behaviours is such that very few of the outcomes are convincingly proven, things like prevention of respiratory tract infections, diarrhoea, NEC are solid but things like obesity, asthma, eczema, diabetes are much more shaky and may at the end of the day not come out as truly a causal effect of BF versus FF feeding.
However, in my opinion communication of this is not as cautious as it should be to families and clearly from this huge thread there are many families where the impression is being conveyed that feeding formula is in some way actively harmful, which it isn't. (in a country like the UK - OK, South Sudan maybe).
My experience was that many BF support people are kind, huge numbers of them don't go down the road of exaggeration and genuinely are basically there for families and giving the practical help they can. But this isn't helped by the wider rhetoric of promotion and some of the more vocal people who are really talking about the UK's breastfeeding rates as being a public health crisis, which it's far from clear that they are.
Personally I feel that potentially much more harm may be being done by overexaggeration of the harms of formula feeding, which at the very minimum just causes families which do end up FF the baby (who obviously, goes on to do JUST FINE) to distrust this area of health promotion and sometimes, that they don't get the help they need from HCPs to support safe feeding of the baby.
