I actually take a lot of what’s Samourai says with a grain of salt too. I stopped using them when it was shared/suspected that the mobile wallet was sharing the xpub with them, and they just went on a spree of insulting people.

That doesn’t mean it’s true, but I couldn’t see anywhere that they denied it or explained why it would look that way. Maybe they are just rage Twitter users, but the convo of no clear answer to the claim & reacting like, with respect, fools - and over an issue that would essentially make their privacy wallet have the exact opposite of anything remotely private… just really turned me off. I haven’t gone back to them since.

I’d love to be proven wrong, but I’ve not taken the time to look into it again & it seemed like the one group with the incentive to prove it wasn’t interested. 

I’ll look at the published data when I get a chance. Will be doing an episode on privacy stuff soon anyway so it will be good to look into.
