In addition to the conflict of interest Moxie has (and, honestly, I can see that side -- of course he'd want to be involved in the cryptographic design of a privacy-preserving payment system -- but he still needs to come clean about his relationship with MobileCoin), the most disturbing thing to me remains that the source to the server wasn't publicly updated for nearly a year while they added this feature, the timing of when the source went dark clearly indicates that specific intent, and Moxie's statement as recently as January that they didn't have specific plans to add payment/cryptocurrency when it's clear from the server source that they had been working on it for many, many months at that time.
As usual, it's not the crime, it's the coverup.
