Each time I see “cyber” used in a headline (so far it happened once) without any other hints that it’s about security, I am initially confused. What is wrong with the term “infosec”, exactly? Clear, logical, well-known and most widely used term to mean—you guessed it—information security.
There does not have to be a term committee or term police for colloquial use, but to me referring to somebody calling it out when terminology makes no sense as “making a stink” says something about the objector.
Cyber expands way past infosec. And that's the crux of the problem with the complainers these days. You don't understand the full picture. You've convinced yourself you do. And so you tilt at windmills like an idiot.
