Related, but different, & if there's someone at Google looking at this:
There was a Titan Bluetooth Key (for 2FA) Vulnerability, you've said you'll replace the affected keys[1], but you're no longer doing so. Which is frustrating.
You'll have better luck with a separate post, even if it doesn't hit the front page. I would over-describe the problem, state it in 3 different ways, so some kind soul searching is more likely to find it.
