Now I see why it was so confusing. This organization, "Hacking Team", chose a name which is really awkward. In most cases, "hacking team" would be a common noun and appear with some kind of article before it (e.g. "a" or "the"). Since it's really acting as a proper noun, it must appear without any articles. I was assuming, as many people probably would if they didn't happen to read the article just before the poll, that the poll title was just a poorly composed sentence which meant to ask the question "Are the activities of hacking teams ethical?"
