Mommies, is this lady wrong?

I was at the mall with my pregnant friend yesterday for some last minute baby shopping. When we got to the formula and bottles aisle, I saw a pump and asked if she was planning on feeding and she said no. She didn't feel comfortable with it and this lady who was pregnant and her friends made a snippy comment of how Lynsey ' Let a man suck on her to get pregnant but yet couldn't give to a baby who needs it and how she felt sorry for her baby' We were shocked. Who was this woman to tell her that and speak to her like that. Lynsey replied to her that she felt sorry for her baby for having a mother liked that, then we bought our stuff and left. When we got home Lynsey started crying, i felt bad when she asked if i thought she was a bad mother, I told her to do what she felt right. Then i asked if she was rethinking her decision and she said no, but i think judgement is getting to her with this being her first child. What do you guys think?
