It sounds funny to claim a license that grants rights to users, but yet
states "All rights reserved" that sounds like you are NOT granting
rights to others.  These days, it has lost all legal significance, and
is merely adding noise:
https://www.iusmentis.com/copyright/allrightsreserved/

With BSD license, it is a historical accident of copy-and-paste; where
different upstream sources of the license differ on whether the phrase
is still part of the license:

https://spdx.org/licenses/BSD-2-Clause.html
https://opensource.org/licenses/BSD-2-Clause

Thus, I can overlook it for BSD files, but I hate seeing it on GPL
files, so I try to point it out whenever I notice it.
