Wikipedia is the encyclopedia that "anyone can edit." Although it might fly against the prevailing opinion online, I would not classify a one-word edit like this as a defacement. Whether Snowden is a dissident, traitor, or some other word (patriot?) is really a matter of opinion.

In the US we have a specific definition for treason which makes it pretty clear that Snowden is not a traitor.

Well, pretty clear that they'll never prove Snowden is a traitor in court, at least. ;)
