Just want an opinion.

So my husband completely cut off his toxic side of the family over a year ago for numerous of reasons. My husband has a friend who is also the father of his sisters oldest son. Theyve been friends for 12+ years. This friend comes over here often and hangs out with us and our children and he also goes over to my husbands moms house where the oldest sister/son live at. So he’s mutual. My husbands side of the family have a history of going through other people to get insight on us such as pictures of our children updates etc. Lately I’ve been noticing that my husbands friend has been taking pictures of our kids but being low key about it. I know for a fact that my husbands family is asking him to send pictures of our kids to them. My husband spoke up and told his friend to not take pictures of our kids and send them over to them and the friend said okay and agreed with not doing that. But now, we have another person who sees both our family, and his side that we are not speaking to. This person came over on Christmas with my husbands sisters son(unexpectedly, but we love him and don’t mind him visiting at all) and has never asked to take pictures of us or our kids with hers until just now. We know she’s close with his side, so my husband messaged her stating “Thank you for coming over to visit and and for the gifts! We do want to tell you to please don’t forward any of those pictures over to my family as we don’t want them having any pictures of us or of my children”. This person ignored what he said and replied with “the kids loved the gifts you gave them, thank you. “ So my husband responded with “thank you for respecting our decision! I’m glad the kids love the gifts (:” “

are we in the wrong for setting these types of boundaries for the privacy of our family?
