i feel formula should be a last resort not the first choice as it is processed and breast milk is more natural......
And I guess others feel differently and that's their prerogative.

I have very strong feelings about how I feed my baby, but the choices others make is not business. I have no idea how or why they came to their decisions, so who am I to judge?

I agree with delphmoon, if you really want to know go and read the hundreds of heated threads on the topic in both the bf'ing and ff'ing areas.
