Global is difficult to define. The issue with globals is not that they are global, but that they have a shared mutable state. We should be switching from saying global variables are bad to shared mutable state is bad.
I've been a professional C, Perl, PHP and Python developer.
I'm an ex-sysadmin from the late 20th century.
These days I do more Javascript and CSS and whatnot, and promote UX and accessibility.
I want to agree, but I've seen the result of this as well, such "single modifier" principles. You end up with a bunch of code that hides variables only to expose a set_x( value ) { x = value; } function -- missing the fact that it makes x a shared mutable variable.
Though I'd say the notion of ownership and control is important, and should be on a list of essential knowledge for programmers. Just like lifetime and visiblity, it plays a major role in where variables are defined.

We're a place where coders share, stay up-to-date and grow their careers.

I'd say "global" simply means "not namespaced or otherwise explicitly scoped".
When you look at it like that, they're untethered, untrustworthy and unnecessary.
