they may have already created a backup of our seed
This is why I never fully trusted hardware wallets. I can't possibly know for sure what happens inside the black box.
This is why I only trust old equipment but sadly in near future I'll won't be able to use them. I personally believe that when computers, mobiles and softwares were at an early stage of development, real aim and priority was to improve the technology and make things better but once there is a lit of potential to earn billions, then this takes over every positive thinking and real aim becomes to improve technology in order to gain more control and influence.
I simply can't trust modern hardware, I'm afraid highest percentage of them are backdoored. I prefer to create and hold my bitcoin wallet in a 2008s personal computer than in modern Intel Core i5-13400 with RTX 4090 GPU.
Btw I have mentioned many times that the level of security depends on the level of asset value but the hardware wallet and KYC accident now really makes me think twice.
