Doesn't bother me that advocacy groups have corporate sponsors, they all do. Makes sense, since the industry that springs from a lifestyle or vocation or right has an industry that supports it. The big dollars for advocacy come from business. It is up to an individual joining a group to ascertain that it is not under undue influence from corporations, if it is, then one make a choice to not join, join and suck it up, or form one's own group or join an alternative one. It's called personal responsibility.
