I completely agree with all of his conclusions. I regret ever suggesting that anyone should buy a Trezor, and I will never do so again. They have shown themselves to be anti-privacy and anti-fungibility, and are therefore not just selling out their users but are actively working against bitcoin itself, in order to line their own pockets.

As he says, however, if you already have a Trezor device (and no other hardware wallet you can swap to or can afford), you are probably safe to keep using it provided you don't go anywhere near the coinjoin feature. I also don't have a single shred of trust left for Trezor, though, so I would make sure you are using it through something like Electrum or Sparrow pointed at your own node and absolutely not relying on Trezor's servers. And when it comes to the time to upgrade or replace your hardware wallet, obviously do not buy another Trezor.
