I will just explain what it does. It takes away from the definition pure activities of “advocacy, protest, dissent and artistic expression”. It's to make clear that we don't wish to capture those when sharing information.
However, we did modify it to say that if such an activity were conducted in conjunction with an activity that is captured in the definition, we can then share information about that particular activity. We think that reaches the right balance in respecting advocacy, protest, dissent, and artistic expression, but also not being prevented from sharing information when we need to, when there is an actual threat to national security.
