Well, the only software you should trust is on the hardware.
Which is why hardware vendors constantly prompt you to verify what is on the device screen, and not the attached host.
I meant more as an attack vector in general (virus, etc) more than just being able to steal your bitcoin. I try and keep the software installed on my machines to the bare minimum required and there should be no reason that I need to install bloated software in order to use a hardware wallet. I don't want to use their platform to buy and sell bitcoin nor do I care about all the other sh*t coins.

All fair. Trezor also has BTC only firmware.
