Wikipedia is not the best source of information. There is a difference between "strong" copyleft and "weak" copyleft. An example of "weak" (non-viral) copyleft is the CDDL. In fact, the CDDL's Wikipedia page talks about strong and weak copyleft. You can read [1] for a breakdown of copyleft by an actual lawyer. Suffice it to say that Wikipedia's Copyleft page is woefully inadequate.
