There was once a time where you had a workstation running a professional OS you could trust not to mess with your data and privacy. I think we lost something there.

Yes, we lost something as soon as applications could start doing things without explicit instruction from the machine's owner.

Limited technology (pre-HDD) accidentally gave us privacy (data on disconnected floppy disks) and security (OSs on ROMs).
