Still off. The NSA’s behaviours made this decision happen. Snowden exposing those behaviours isn’t really relavent.
This was proximately caused by Snowden disclosing what the NSA was doing. It was ultimately caused by NSA monitoring major swaths of the population.

I’ll still argue for ultimate cause because if it wasn’t Snowden it seems likely would have been someone else.
I’m a firm believer in don’t shoot the messenger, even if they are flawed.
