Or, and hear me out before pitchforking me please...(🙏)...

ZBD isn't aimed at Bitcoiners, they're a games company that rewards users with bitcoin and is introducing social features.

The people they're aiming at are the ones who want easy recovery options that they know and love and that means at the very least keeping a copy of the nsec and allowing people to recover everything via email, which they're used to.

Good or bad in anyone else's eyes doesn't matter to the company if the companies target market isn't them.

At least once they're here we can encourage further exploration and adopting their own pub/priv key set up. If they're put off before arrival then we don't get chance to show them the better paths. We might as well take advantage of the availability of non average bitcoin and Nostr user's that ZBD and others will bring.
