I don't think there's a need to be confused here. Parent liked it when the tool empowered them, but most people don't like when tools give others power - potentially power over them. The difference in like/hate is in how the tool is deployed. If the only use of facial recognition on Facebook were to track how one's own image is used I don't think many people would be upset. But allowing someone else to find every image one appears in is a different and scarier thing.
