I never said Bisq has servers, but you still need to have some level of trust with anything you use.
Not to get too far into the weeds, but there's very little trust required to use bisq other than having to trust the selling bitcoin for fiat won't result in a charge-back. But that requires trusting the other trader, not the software.
You can't really know that anything you use is not spying on you all the time, so it's not fair to claim this only for wasabi wallet.
There is the fact that Wasabi admitted they will be scrutinizing your UTXOs for taint. The term "spying" may be a bit of an overreach when it comes to Wasabi themselves, but if they decide many of your UTXOs are not to their liking, they'll have enough information about your wallet that can be provided to the authorities who can possibly use that information to determine your true identity.
Everyday smartphone is 100% spying device, yet nobody seems to mind using them all the time.
When I'm hunting deer I turn my phone off because I don't want Google executives knowing about my honey hole.
Well, Trezor builds hardware wallets, and Wasabi is a coinjoin coordinator, those facts we know. My sharply honed powers of observation leaves me with little to surmise other than Trezor plans to integrate zksnacks' coin-join into Trezor Suite. Call me simple.
Wrong.Wasabi is not coordinator.
zkSNACKs is coordinator.
Okay, so I conflated the two entities, but lets not argue about semantics. We both know they're essentially one in the same. I suppose it's possible that Trezor doesn't want to maintain Trezor Suite going forward, and would rather promote Wasabi as their official wallet, but I doubt that's the case. Even if that was the case, the end result would essentially be the same thing, i.e Trezor's official wallet including zksnaks' coin-join coordinator.
