I never heard about #ElsaGate before. There is obviously a pedagogic message in the videos. The main problem seems that leaving the kids unattended watching these videos doesn't work here. Similar to Grimms' Fairy Tales or children stories from Shockheaded Peter. Parents need to read these books to their children in order to give them feedback. I've read some texts by Prof. Dr. Stefan Aufenanger from University of Mainz about this topic.
EDIT: Of course, in order to explain things to kids they need to be in a certain age. The videos seem to be targeted to children in pre-school age.
