b) This is a very, very watered down form of "protesting against injustice". You're essentially attacking one person and trying to boycott the decades of seminal work by a non-profit foundation for free software over one morally objectionable act. One that he does not seem to bring into his workplace, and one that by the way, got ruled unconstitutional and overturned. It has no present effect on anyone.

Of course, it is remarkably less difficult to do that, while still flying under the guise of a greater cause.
