Both ViaBTC and Bitmain have been supporting the New York Agreement from the start. Planning a UAHF on the 1st of august seems not in line with that agreement. The market was very happy when the SegWit2x compromise finally got all miners aligned. If ViaBTC and Bitmain now support a UAHF that seems to me a sign of unreliability and I am sure the market will not be happy with this new controversy. It will not be good for the general image and the acceptance of the bitcoin.
