"You have absolutely no knowledge, way to check, or guarantee that EVERY EMAIL YOU SEND isn't already doing that anyway."
So being an asshole is OK because it is possible for some people to be assholes without me knowing - what an asshole.
"People sending email to any of Google's 425 million Gmail users have no "reasonable expectation" that their communications are confidential, the internet giant has said in a court filing."
Which is why people using gmail are assholes and businesses using gmail are stupid and assholes.
