It is more like a legal question.
Reading EC261 literally, EC261 will not apply any U.S.>Europe flights. However, Canada views this differently and decided all passengers should be treated the same, and thus extend EC261 to all Canada>Europe flights as well.
While UA is apparently exempted, you may be able to argue that it is an unfair treatment. But again - is it really worth to push that far?
