Possibly due to her being 4 y.o. and being assaulted by someone in a position of trust, someone like her brother who clearly demonstrates the willingness to violate other people's trust as an adult. His actions today are probably a result of the absence of consequences for bad behavior earlier in life. He learned that he can do these things and get away with it so now he manipulates as a normal course of action.
These accusations are just another validation that the entire cancel culture thing is more about pushing politics than it is about punishing evil.
