The irony is supreme - if UASF will have even the slightest chance of "success" (by that I mean: splitting the bitcoin chain and causing havoc in the space, mostly just a shorting opportunity for investors), they'll need to buy a bunch of miners from Jihan Wu!
Well, the UASF chain would no longer be kept hostage with covert ASICBOOST, which to my knowledge, segwit totally fulminates.
So not only UASF chain is better technologically due segwit, but it is no longer kept hostage with what is basically a 51% attack.
In any case, you don't need to buy mining gear from Jihan:
