Thank you for your comment, it is very thoughtful.
On looking at that transaction my initial reaction is.... wow that's a pitiful coinjoin.
There are 3 outputs that are the same meaning that the anonymity set is... 3? That's not good.
Joinmarket's default settings I believe has an anon set of somewhere between 8-10. And so imagine if there are 10 outputs of the same size, with a few other outputs of various sizes... it seems to me it would be difficult to determine which sats belong to whom.
Especially if there are other coinjoins or 'maker' transactions before or after with the same outputs.
Exactly, I cherry picked that JoinMarket tx for the demonstration because it is very small. Here's a very large JoinMarket tx where it's more difficult to determine the set of inputs linked to the users who created the bc1q...f2yxq and bc1q...xvdwu change outputs: https://mempool.space/tx/63b28f5e17e03fef27795e1ea7fbf821e2d5f072098ffcef3d27b8b2d23ca719
