> joining an advisory council is not the same as lending support That is your opinion, but it's not fact. I'm sure you are aware that many disagree (who have no greater claim to fact than you), including the people who bought that billboard and those who pressured Travis Kalanick (of Uber) into leaving the advisory council. It's really a matter of degree. It says that this is a person who is worth the time to advise; they are therefore intelligent, responsible, capable, they listen, and I share their values enough to associate my name with their endeavors. It doesn't say 'I support everything they do'. If Musk joined advisory council of most businesses, it would send an incredible message of support, for example (though not exactly comparable).
