Not that I consider the overall sentiment of the linked article wrong, but this...

> Dereferencing a nullptr gives a segfault (which is not a security issue, except in older kernels). Dereferencing a nullopt however, gives you an uninitialized value as a pointer, which can be a serious security issue.

...betrays a complete lack of understanding what Undefined Behavior is/implies. That's not something you want to see in an article discussing memory safety.
