That's close to, but not quite the point. Let's say you're happy with your chef's output at work. The chef is making good dishes, and suggests changes and new items. Great. You ask, when the chef comes in for the day, what he or she did over the weekend. "Well", comes the response. "My in-laws were visiting, so I made them a proper Italian supper, with fresh pasta and homemade meatballs." Your restaurant isn't Italian. Are you annoyed? The point is that it's wrong to control people when they're not at work. If you're happy with a programmer's output at work, it's ridiculous to tell them that they shouldn't program when they go home. If you're unhappy with their work, then the point is not "you're doing too much at home", but "you're not doing enough at work. Do what you need to do to produce as we agreed your job requires."
