Sure, they could. Things can always change for the worse in the future, but at least now the default state is different. Knowledge that something may change in the future doesn't render everything in the present futile, even for symbolic stances of self-governance. This is certainly toothless symbolism, but it doesn't make it meaningless. It's a reaction to the disgust most of the membership felt towards the organization. There will always be individual psychologists that will do what they're paid to do anyway, but I'd still prefer the body with the biggest political influence stake out a "not horrible" position on any given subject.

Relevant name for the comment, by the way.
