Federated Machine Learning

I am curious on what others thought are on using a federated model to further increase privacy for those willing to share their data. I have heard mized sentiment on weather sharing trained model data vs raw data is that different in the privacy aspect, but in terms of simplicity of training it seems fantastic (for the end user).
