no, they want to pretend this is the issue, so that pervasive monitoring or permission and/or deanonymization is normalized. It is to serve the state apparatus, rather than any actual protection.
If it is possible to "pretend that they want something reasonable", it means that there is something reasonable somewhere.
Maybe some want more control, but most certainly not everybody.
> so that pervasive monitoring
If you haven't gotten the memo, pervasive monitoring already exists. To sell ads.
