The line between private and public has been crossed many times but we're still better off having that line officially there.

Even if the cops and private security along with TLAs are actively spying on people on an extremely regular basis, we're better off if officially they aren't supposed to be, if some court cases can get tossed for this, that they have to retreat sometimes, etc.

This is why having Apple overtly spying on the "private side" is still a big thing even with all the other revelations.
