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.
