Because in this position, he's a visible public figure and community leader, and in the past he's been actively campaigning for the removal of certain civil rights from members of the organisation he works for. In my opinion, that requires an apology and public statement that such policies will not be promoted as part of his work with Mozilla. If that isn't forthcoming, it seems perfectly reasonably to perform "civil disobedience" as it were.
