Negative. There is very little good scientific evidence that it is important to breastfeed. But even if we stipulate that mothers must breastfeed, many working women pump milk during the day if they don't have unlimited paid time off after birth. In such cases bottles must obviously be used. And many women cannot produce enough breastmilk, and must supplement with formula. And many other possible reasons why bottles must be used.
Anyway, one thing we can say for sure: if it's not your kid and you weren't specifically asked for advice, don't tell someone they should have been breastfeeding.
