the situation is not very good for bitmain atm

It's funny how obvious Bitmain money is on that list. Bitpay got bribed by Bitmain, which is why Bitpay signed the ridiculous NYC agreement as well. Now it's a matter of time to see if the rest of actors are reasonable or go along with the BitmainCoin hardfork.
Yes, UASF is not ideal, but BitmainCoin hardfork is worse. At this point you might as well give people the opportunity to take control over their private keys, may a soft fork happen in august 1st. It's only safe to take preventive measures. Let people choose if they want Legacy coins or BIP148 coins. It is not a hard fork after all unlike the Bitmain mess.
