This is talk about how the OS uses that RAM to make your software better.

But to that point, having to explain to people why this 32GB machine with two processes using 10GB each can not, in fact, fit another 10GB process because the response times of the two existing processes relies heavily on that “unused” memory that is actually part of the working set of the machine. And also occasionally one of those services spikes to 14GB so what happens when that happens?

So in that regard showing that memory as used has advantages for avoiding arguments with people who are not equipped to have their half of the argument in a useful and meaningful way.
