This is true, which is why it makes sense at the $25 promo price.
At the $150 asking price, it's a tapsigner with an added fingerprint sensor, but with additional tradeoffs and vendor lock-in.
I can only see this being a useful product if they keep the current model for entry-level users and unlock it for use as a blind signer for any multisig setup.
> if someone has hijacked your phone and what appears on its screen.
this is common for all blind signers, not a bitkey specific issue.
Any blind signer can be turned into a non-blind one with 2 things:
1. Extra code in the signer to check if the sign request is signed by the screen device
2. A screen device that shows the transaction, and produces a signature for it if approved (this can be less secure)
Yeah I agree if it was $25 it makes a lot more sense.
However I think other blind signers are marketed differently and sold to a largely different audience. My guess is people buying say a tapsigner and using Nunchuk are more educated on these trade offs.
