The fight against facial recognition will be a back and forth between the facial recognition itself and algorithms trying to prevent it (like this one). One issue is that parties using facial recognition have a big advantage: They can run new algorithms against old pictures.

Tools like these might be useful in some cases, like preventing stalking _right now_, but can't (sadly) guarantee a prevention in any way for the future.

I assume this tool will be marketed differently.

The problem is more in the case that if you have access to the ground truth data, and use such a tool to create images without detectable faces, you can artificially create more testing data. In the end this training data will be more robust, and the underlying method, like any form of CNN, will be able to generalize better.
