Wow, the fact Reddit is claiming he's blackmailing them for 10 million dollars is insane.
The fact the dev recorded it and posted it online for people to listen to themselves is great. God I love living in Ontario Canada where it's a single party consent to record others on the phone.
I live in South Korea where it's also legal to record only with single party consent. It's not that long ago that I found out that it's not a universal thing. It should be.
