I'm going to throw a new possibility here into the mix. DD's fight with Moria post-Marineford keeps eating at me. He said someone higher than Sengoku ordered him to at the time. I wonder with the Tenryubito's ties to his slave auction house if he didn't gain a powerful ally or two near the top. So here's the possibility (not prediction) that perhaps the WG knows about DD's artificial devil fruit production and is having him taint or poison the fruit to slowly weaken and kill Kaido's crew. I gotta think taking a Yonko down is a pretty high priority for the Navy and if someone higher than the fleet admiral trusts him to do the job then the Navy will just have to take out the StrawHeart Alliance for getting in the way.
