Yes. Yes, it's a bug if there's not a GUI way to do a thing that a user wants to do. I am of the opinion that the advantages of Ubuntu being wildly popular all around the world are advantages that I want to see -- much better hardware support, much better software support, no longer being a second-class citizen in many things -- and that most people are not interested in using the CLI, and teaching them to do so is the wrong approach.

As you say, it IS perfectly possible to win with free software, to love free software, to be its passionate advocate, without caring that someone else loves proprietary software. But not everyone does. And the people who castigate you make the environment so unpleasant that they're what drive you out. It seems that the "advocate open source" model has become, for some people, the "chastise those who are insufficiently dedicated to open source" model, and hearing that all the time is very, very tiring. It doesn't matter if there are a hundred nice people for every one nasty person, because you never get to hear from the nice people, just the nasty ones. And there is no culture of nice people calling out the nasty ones and stopping them doing it, because then the nice people look insufficiently dedicated and so become targets of zealot ire too.
