And who is "brian"?
Brian Smith, the one who started it to begin with. Later I (teozkr/nullable) and Fluffy (Fluff-Is-Back) joined as well.
EDIT: I don't think that BlockOS was ever copyrighted so uh yea
Copyright in pretty much every industrialized country on earth is automatic and free, with a default all-rights-reserved (can't do anything without the copyright holder's permission) license. You (and many others) are confusing copyright with patents.
