I don't think it is reasonable to expect every user (including those just starting out with the tools - maybe experimenting, maybe younger/less experienced in general) to think that the tool they're running for the very first time is going to automatically exfiltrate all of their data.
It's a pretty serious fuck-up. This guy tweeted about it, who knows how many didn't even notice. It should have been opt-in, it should give user an indication that it's about to do this, etc.
