Unless I'm missing something, there's not an obvious way to "spy" on employees, which this article is claiming. Perhaps it's possible, but if it is, it would require a lot of deliberate effort to accomplish. For example, there's not an out of the box way to track employee location. There's not a way to track employee internet browsing history out of the box.
TLDR: using G Suite Advanced MDM, there are not out of the box solutions for tracking or spying on employees in the ways suggested in the article. It might be technically possible, but to accomplish it, your company would need to make a (large) deliberate effort to do this.
