You can scale Bitcoin to a fair extent without modifying the block size. Segwit -> Schnorr + Signature aggregation -> LN/sidechains/TumbleBit/Mimblewimble.
This is exactly what Bitcoin needs, the only one who's blocking it is that anoying little brat called Jihan Wu.
Entirely correct, and we can absolutely butcher him for this. I don't want to advocate vengeful behavior but it is tempting.
None the less, a UASF means he just has to play fair, it doesn't make his equipment useless like a PoW change would.
UASF is a peaceful way to counter an aggressive attack.
