Wu have been supporting BU from the start and now the crash in price create a panic among the users. Now once again a sudden increase in circulation happens causing delay in transaction confirmation with the increased traffic on the selling. Right now nothing can be done as the segwit has gained around 30% support from the miners.
"Officially" getting Antpool definitely scores for BU, but if it has been always clear communicated positions this rage-dump should be short tempered and short lasting in result. Markets allready back on a rise again.
Hashrate did not even react.
