Looks like he is gone since lats week

Brock Pierce was an early advisor to Block.one for several months and made significant contributions to the awareness of the EOSIO project. His past experience working with projects such as Ethereum, Blockchain Capital, and as chairman of the Bitcoin Foundation have proved immensely valuable. As we mentioned last week, we recently came to a mutual agreement that Brock would end his role at Block.one as he transitions to independent community building and investment activities. We thank Brock for his contributions, support, and continued larger than life passion for the EOSIO project.
