"and the disallowed "my child turned out OK on formula" anecdotes that aren't allowed "because they're just anecdotes" in here as well"
Actually there are literally tens of thousands of these anecdotes which are wheeled out on mumsnet every fucking time sometime anyone makes an informed argument for breastfeeding having benefits and backs it up with some research references.
And actually, it's incredibly reassuring. No formula fed child on mumsnet is ever ill. They all grow up into incredibly healthy, brilliant adults.
The marvellous thing about this is that as most children in the UK over 6 weeks are fully formula fed, we can stop worrying about the NHS. Who needs it when no formula fed child is ever ill!
Except maybe it's still important for the legions of sickly breastfed children out there that you hear about on mumsnet during the ff/bf discussions - you know, people's exclusively breastfed neighbor's/friends/SIL's kids that are always bloody poorly and underweight. 
Ho hum.
However, it's good to see that there's a fair bit of insight on mumsnet into the hateful profiteering by formula companies. Their marketing strategies in developing countries are awful and even in the UK it's pretty unethical, particularly when you keep in mind the fact that a disproportionate number of their customers come from the most disadvantaged groups in society.
One of my motivations for exclusively breastfeeding my two younger children was to avoid handing my cash over to these bastards.
