Well... not yet (it was just a thing that was bugging my brains today). BUT it might actually be going that way still. Why?
Do you remember as a child or teenager that every time we preached and asked when it would stop the answer would be: "till Jehovah tells us it is no longer necessary"?
The amount of literature is dropped... there are no old bibles... they sell all kind of keylocations all across the globe etc etc etc ... all money is getting centered to one spot one way or another.
Also... if shit is gonna happen worldwide (maybe a "normal" world war or something) it is actually not a strange thought that one day soon they may announce something like the following:
Brothers and sisters... we have now officially preached till the end of the world... armageddon is coming this very moment... we stop the presses and all kingdom activities since from now on it is in heavens hands... we see your sorry asses in the new world and will contact you then...
It would be the perfect excuse to make an exit for them.
