It's disingenuous though. I mean they sell it as super duper anonymous, while random SPV wallet devs don't.
I agree with you to an extent. Yes, they promote themselves as a privacy wallet, but their website is also pretty clear about the risks you take by not running your own node and the benefits to be gained by doing so. If you go to their website, immediately under the initial blurb about the wallet itself are links to Dojo. The Dojo makes it clear that you are risking privacy if you don't use Dojo:
Samourai Wallet is already unrivaled in transaction privacy, but the default configuration is still subject to network level privacy loss. Hosting your own Dojo allows you to simply bypass our default servers and circumvent these concerns.
So yeah, perhaps this information should be more visible, but they are not actively hiding it.
This is only a small mitigation in my opinion because we will face the same conundrum as we face in something like Electrum (although Electrum isn't privacy oriented).
So what's the solution here? Every user running their own coordinator, all of which communicate with everyone else's coordinator in a decentralized manner, much like the bitcoin network itself?
