Not actually open source. The source code that’s available is a thin wrapper around a closed-source ML model. If George really cared about Open Source he would release the training architecture and training data.
As somebody who works with video and photo user data for machine learning, I'd say they are much better off not releasing the majority of their data. Unfortunately there are fairly severe legal consequences for commercial use of certain kinds of unconsented user data in various US states (consent of the people filmed, not the people collecting the data), and even companies in complete compliance have to deal with a huge potential legal headache to prove that their datasets follow every local regulation.
