Regardless of the rights or wrongs of decisions made, appointments etc etc. those that think the chair or board of directors have any responsibility towards the fans knows nothing about company law. The only responsibility they have is to the shareholders, and to a lesser extent, in the case of a football club, to the rules of whatever league/competition they compete in.
This is simply a hard fact like it or not. Morally, it may be wrong in terms of history and culture etc but that's life.
People can protest and cry about it all they like but ultimately it makes no difference.
If you feel that strongly, the only way to really bring about change is to buy enough shares to entitle a meaningful vote at the agm etc. Football clubs ARE businesses, and companies, not some sort of heritage charity run by groups of well meaning volunteers.
If you don't like the product, don't buy it. There are plenty of others that will.
