Those interested in adoption should be _so_ interested, that they're willing to go meet in-person with an agency who can introduce them to the children.
Charities use images of children to sell the charity.

Note that they're not selling the children.
That's what everyone would like... except that even if they are sloppy (not saying that they are) there's still a lot of children that are never going to be adopted. Do you believe that's better? Spoiler: it's not, because you're making sure most children will have a disfunctional adult life (growing up without a family is extremely hard) instead of allowing more children to live a normal life, but with the increased probability of a few living with bad parents (the number of cases where that's worse than no family at all is probably very small).
