I guess it depends on how you look at it. In your first case, I think "enjoy" may be a better word. I enjoy playing The Sims in my underwear, but I want to use, say, Wireshark. Do I enjoy using Wireshark? Yes, because I'm a freak. Still, I think most people would say no. In my field, Wireshark isn't a tool you bust out when everything is working perfectly. Does that mean I don't want it? That I don't like it? That I wouldn't be more than willing to pay for it, were it a commercial product? Of course not! It's more nuanced than that.
