I've seen this way too often.
- Q: How do I make Vim use the system clipboard?
- A: `+"*yy`
- Q: That's annoying, why is it this way?
- A: It's not annoying, what's so hard about typing that?
This advice seems to be almost ingenuous, and it seems to bespeak a serious cluelessness. Copying a line, an action so common that there's a special syntax for just that, shouldn't need 6 keystrokes (shift keys count) to type. It's entirely reasonable to assume a piece of software that runs on an operating system has its common actions compatible with the rest of it.
The fact that the d key actually cuts text is entirely unintuitive
and a default behavior that makes the x key a real pain to use since
it ruins your yank buffer.
