> All Trezor devices are distributed without firmware installed - you will need to install it during setup. This setup process will check if firmware is already installed on the device. If firmware is detected then the device should not be used. [...] The bootloader verifies the firmware signature each time you connect your Trezor to a computer. Trezor Suite will only accept the device if the installed firmware is correctly signed by SatoshiLabs.
This is an absurd security model. Where's the root of trust here? How do I know I am initially talking to an authentic "blank" device, and not a malicious one pretending to be one?

Hopefully, malicious firmware won't meddle with this feature in any way...
The vendor here is either completely clueless, or is trying to paint a better picture for prospective customers despite knowing better.
