I will write here the same I wrote under Matthew's video...
...on this one I have to disagree. I think your view on this particular matter is very black & white. Let me add something to it:
1. It is completely voluntary to use coinjoin feature in Trezor.
2. Nobody, not even the coordinator knows who you are. (As you are hidden thanks to tor and block filters)
3. I spoke directly with nostr:npub1klkk3vrzme455yh9rl2jshq7rc8dpegj3ndf82c3ks2sk40dxt7qulx3vt and listened to people from Trezor ( nostr:npub16lcw8ytugeh3ug3na93yl0tdf0gnjtduljhn2a852atf6jtvkucs7pruje and others) explaining their point of view on coinjoin with WabiSabi.
- zkSNACKs/WabiSabi was chosen because - as stick put it, it is superior coinjoin to the Whirlpool in the sense that WabiSabi coinjoin is a superset of Whirlpool. Meaning WabiSabi can do everything Whirlpool can (potentially) but not the other way around. So from a future point of view, in regard to potential functionality, this was a better coinjoin solution to go with.
- Both Max and people from Trezor would much rather use coinjoin which does not follow OFAC transaction censorship. It's disgusting. Everyone agrees. But as zkSNACKs is a company that could and already was harassed by law enforcers in Gibraltar, it was decided that - at least for the time being - it will follow OFAC regulations to avoid this while providing pretty good privacy feature to the masses.
4. Another kind of "feature" is that Trezor users can for free check their UTXOs if any of them is blacklisted by OFAC. (If it is, it will be refused when trying to coinjoin it) This will tell users upfront and they will know to be potentially careful to not send such UTXO to exchanges to avoid freezing of their funds or even an account. And they will know that such UTXO should be handled differently - eg. leveraging the lightning network. (I guess that should help...)
I really do not see this one to be so bad. Trezor works just as it did before. But on top, it enables pretty damn good, one-click strong privacy feature to all its users. This feature does not leak information about you to anyone. But it does not let you to use this feature when your UTXO is on OFAC list. You will find out for free, without any issue and you can deal with such UTXO separately.
