But who is going to trust Facebook/Meta with everything?
Even my parents are wary of their products.
I can't see a personal assistant coming from them and being successful.
They care but then it has been made very difficult to find privacy preserving services. Or convenience takes over.
It is like replaceable batteries. Everyone cares but we are not given the choice.
Or the headphone jack...
I think it is different here. First it is easy to build. Second that is too much information that should remain private.
