I did a lot of work on iCloud’s “Hide My Email”, and I’m involved (the DRI for) quite heavily in other privacy-focused work at iCloud. It’s something I feel strongly about.
It's generally fine to talk about something already public, and say you worked on it - there are projects that haven't released yet that I've worked on, and I absolutely will not talk about those until they are :)
It's not worth trying to retaliate because these things come from addresses that aren't monitored, for the 99% case...
I do make a point of telling people how shitty the company is though.. Like Tesla for example :)
Oh and none of the involved entities ever acknowledged the leaks. I'd also be highly interested in the rates other people encounter.
I get a ton of spam, but they ALL are sent to my publicly listed email address in my git commits. I'm seriously considering turning that email into a honey pot.
The other however has leaked, but that's because it's designed to - it's for social media where the email is available for use and has been abused by third parties.
