You could answer this yourself so it is not helpful to ask such a silly question, but to give you the obvious answer - sure there is child abuse.
Killing freedom of speech and privacy for everyone to get 3 people jailed?
Illegal acting people will just move to illegal platforms and escape while everyone else has to deal with this fool's joke.
Read about the false positives rate on top and it is more then obvious it's a very stupid thing to do.

So just to be clear... you think that in this situation, making no effort to prevent child abuse is OK? You prefer that, to having your data visible to law enforcement?
The one thing I do know, is that humanity includes horrible, narcissistic people and that if you give them the opportunity, they will take it.
You might consider the looong history of the Catholic church, as an example.
