This comment is both factually inaccurate (as other posters have pointed out re: the toilet sensor) and completely misguided. Nobody should need to trust an opaque algorithm running on complex hardware to ensure their own privacy. Even if your beliefs about what Google or another owner would do with this hardware are correct (which I seriously doubt they are, it's far more likely the data will be used as feed-in for machine learning), there is little to no assurance that the police or other parts of the state would not compel surveillance using these devices, nor that malicious actors would not use them for their own ends.
