This is kinda standard practice for many of the tech companies… I’ve had to provide such information to Google, I think I declined last time but it was some rights for Youtube that time, it’s also something that Facebook do ask some users if they think you’re not using your real name…
I totally get your sentiment about this.

I’ve got a buddy that had a similar issue with Origin (now EA Desktop)… He can’t access his games anymore because he used an email that is no longer operated and he has not longer access to it… So he is basically fucked because EA won’t do shit for him.
