This seems like a nothing burger, but a CBDC might be far more harmful as banking services can quickly be switched off, it can also be blacklisted easily ruining the fungibility of the currency so if there is still physical cash you can see a break in value between the two mediums.
In addition, they could also limit what you can trade it for, so I don't see this as a win for bitcoin
I would take the inefficiency that provides privacy any day
I meant it as win, because it looks like they have realized that they need to compete with bitcoin now.
