There's plenty of reasons to want to share images of your offspring besides chasing internet clout, and I find that simplification ignores all but the narcisistic fame chasers that will never care anyway.
Not making any judgement on whether any other reason is particularly valid. Just saying that the people who do it for likes are never going to see it as anything negative or exploitative. Better off talking with or working to stop the people oversharing for other reasons. Higher chance of success.
