Honestly I am surprised at the surprise. There is no possible way to wiggle out of the blood ban, than to slowly make everyone personally responsible for their actions, while not changing the policy of the organization, and removing the negative press and cause for possible future legal action.
THAT is what they have done. You won't be disfellowshipped for it, although that has not been formalized since that would signal change in doctrine.
They can't change the teaching. it will never happen. They can however shift blame, and step away from the mess while limiting their own culpability (in their minds).
