This is a big step towards realization of what the WTS has been counting on, a synthetic product renders their controversial blood transfusion issue moot. They want it so bad they'll ignore that it's made from cows' blood.
Watch for these talking points soon, in a WT (study edition) near you:
1. Faithful dubs followed the Bible prohibition on blood for many years, despite ridicule.
2. Wordly scientists, impressed by the steadfastness of these lovers of Jehovah, set out to solve the problem.
3. Now they've created a synthetic substance designed to save the live's of faithful witnesses everywhere.
4. You see, friends? You just have to wait on Jehovah.
They'll have to spin it for the smarter ones among the faithful, but they've been infecting the ranks with cognitive dissonance for decades. They experimented with the "generation" doctrine and got away with that and to most dubs, the generation teaching had been sacred. Nevertheless, the rank and file were generally willing to look the other way when it mutated into something no one quite understands.
Meanwhile, no one ever really understood the blood transfusion doctrine, so this should be easier for them.
