Other than their Seed extraction vulnerability and the possibility of pushing a malicious version of firmware or Trezor Suite. Is there any thing I might have missed?
They work with Wasabi, meaning they are pro-censorship, they fund blockchain analysis, and they support government blacklists. They were also a big supporter of AOPP, which was a protocol designed to make you KYC your own addresses to centralized exchanges before being allowed to withdraw. They only pulled their implementation of it after huge community backlash. The argument against these facts is always "Well, you don't have to use those things if you don't want to", but it shows their underlying morals and ethos are very much not what they once were. I don't want my hardware wallet designed by people who are so pro-surveillance.
I also take more issues with their approach to the seed extraction vulnerability rather than the seed extraction vulnerability itself. I explain why here:
