Could be, but to be fair their implementation is in line with the DNT draft which says that DNT=1 is a valid default for user agents. Maybe the draft writers didn't think through what the consequences would be for DNT support if DNT=1 became the default in any majority of browsers. The way I see it either the consequences for not respecting DNT need to be greater somehow or the default implementation can't be DNT=1 because third parties will simply ignore it. Without consequences, a default of DNT=1 just weakens the draft and hurts the people who really do want to block everything.
