Trezor is working with Wasabi for Coinjoins, Wasabi is working with chananalysis companies and it uses to the best of my knowledge from the research I have done, peelchain instead of the recommended ZeroLink, it is advised to verify, do the research and not trust. I have done mine and wouldn't touch Wasabi, nor Trezor after this business deal with Wasabi.
Few articles on the matter:
Recommended Book:
  • https://www.goodreads.com/en/book/show/57356067-the-cryptopians
    • revelations from journalist Laura Shin’s new book The Cryptopians, which tracks Ethereum’s early years, showed that Wasabi failed to follow the aptly named protocol ZeroLink.
    • ZeroLink requires “zero linking” of mixed and unmixed Bitcoin. Wasabi used a ZeroLink alternative called “peelchain.” The wallet was released in 2017
That criticism is against Wasabi 1.0, Wasabi 2.0 uses WabiSabi coinjoins, which are different, there is no "toxic change" anymore.
