Anyone know why Theymos didn't think it a good idea to use multisig with the treasurers? This probably means he didn't care too much about the funds that were stolen (especially since there was a 25% reward)... Potentially Theymos just moved on from this so...
I think there was another thread on him to as details of his identity were published briefly by a user here about 3 or 4 years ago. The information was since deleted.
