MrBrew was not walking away entirely from the coin.  He is still a member of this community, and a trusted member of the bitcoin community.  I will reach out about his specific plans for those coins.  However, I would also say that those coins were not a part of any IPO or pre-mine activity.  He rented a super-rig for a weekend and mined the coins, along with everyone else.  So, at the end of the day, those are his.

I would caution everyone not to get hung up on coin donations and things like that, as again there was no pre-mine or IPO.  The WeAreSatoshi coin / concept is one centered around awareness and culture.  Providing donations to charitable causes may occur as members of the community reach out, but there is not, and never has been, a donation fund.
