Stop parroting these criticisms of OpenPGP without offering concrete, working replacements that are widely adopted and have open standards.
Some kid recently tried to have OpenPGP support deprecated from Golang's crypto-x package. And that's fine, but do not pull stunts like this without offering a concrete, working and widely adopted replacement. Otherwise, they are just that, publicity stunts with a lot of sound and fury but no solution. That's not helpful to anyone.
A more mature thing to do would be to suggest deprecation in 3 to 5 years and offer a plan of how to get there with other specific tools (some of which do not exist today).
