Any Brain Computer Interface needs to be locally hosted, non cloud dependent, and open source. A proprietary license can protect the code, but anything touching the brain should be open, transparent, and auditable.
Regarding the second part of your comment, an EEG device like that will have access to way less information (even with state-of-the-art signal processing techniques) than, say, an Apple watch or a FitBit, which have access to tons of biometric information (pulse, ECG, sleep data, constant geolocalization, living habits + much more if you also upload your weight and blood pressure measurements in the companion app), yet the vast majority of the public didn't seem to be too preoccupied when those came out.
