The only people who can claim this is offensive are the people and the family of the people mentioned in the clip. It isn't racist in the slightest, it's more pointing out the racism of the people mentioned for using the kids purely for positive publicity. I'm sure some of the people mentioned actually did the adoption for good reasons, but the clip is definitely accurate for others.
Though it was definitely the right move not to air it, it could easily be misunderstood as racist, as has been proven.
